Explanation: These two sentences must be separated by a blank line. 28. qe-writing-001 - Use one sentence per paragraphLocation: Line 1018-1024 / Section "Sample paths" Description: Multiple sentences appear in the same paragraph block without blank lines between them. Explanation: The introduction to a list should end with a colon rather than just flowing into the bullet points. This is acceptable as a single sentence introducing a list. 29. qe-writing-001 - Use one sentence per paragraphLocation: Line 1026-1030 / Section "Multiplicative martingale as likelihood ratio process" Description: Two sentences appear in the same paragraph block without a blank line between them. Explanation: These two sentences must be separated by a blank line. 30. qe-writing-001 - Use one sentence per paragraphLocation: Line 1032-1033 / Section "Multiplicative martingale as likelihood ratio process" Description: Two sentences appear in the same paragraph block without a blank line between them. Explanation: This is a single sentence spanning multiple lines, which is acceptable. No violation here. 31. qe-writing-001 - Use one sentence per paragraphLocation: Line 700-705 / Section "Peculiar large sample property" Description: Two sentences appear in the same paragraph block without blank lines between them. Explanation: The introduction to the list is acceptable as one sentence, but should end with a colon. 32. qe-writing-001 - Use one sentence per paragraphLocation: Line 709-711 / Section "Peculiar large sample property" Description: Two sentences appear in the same paragraph block without a blank line between them. Explanation: These two sentences must be separated by a blank line. Note the second sentence is missing a period at the end. 33. qe-writing-004 - Avoid unnecessary capitalization in narrative textLocation: Line 77 / Section "A particular additive functional" Description: The term "Gaussian" is unnecessarily capitalized mid-sentence when used as a common descriptive adjective for a type of autoregression. Explanation: After careful review, "Gaussian" appears in the text describing "a Gaussian vector autoregression" where it functions as a technical adjective and should be lowercase as "gaussian" - however, upon further examination, "Gaussian" when referring to distributions named after Carl Friedrich Gauss is conventionally capitalized as it derives from a proper noun (person's name). This is not actually a violation. 34. qe-writing-004 - Avoid unnecessary capitalization in narrative textLocation: Line 101 / Section "A particular additive functional" Description: The term "IID" appears in all capitals when describing a shock, but this is a standard acronym convention and not a violation of narrative capitalization rules. Explanation: Upon review, "IID" is a standard acronym (independently and identically distributed) and acronyms are conventionally capitalized. This is not a violation. 35. qe-writing-004 - Avoid unnecessary capitalization in narrative textLocation: Line 108 / Section "A particular additive functional" Description: The term "Gaussian" is capitalized when describing a vector in narrative text. Explanation: After careful consideration, "Gaussian" derives from the mathematician Carl Friedrich Gauss and follows the convention of capitalizing terms derived from proper nouns (like Markov, Bayesian, etc.). This is actually standard mathematical convention and not a violation. 36. qe-writing-004 - Avoid unnecessary capitalization in narrative textLocation: Line 669 / Section "Multiplicative martingale as likelihood ratio process" Description: The term "Martingale" is unnecessarily capitalized in the middle of a sentence when used as a common technical term. Explanation: While "BIG" might be used for emphasis in the comment, it should be lowercase "big" unless it's an acronym, which it is not in this context. However, reviewing the code more carefully, this appears in multiple places as a stylistic choice to emphasize the enlarged state space. Given this is in a code comment rather than narrative text, this is marginal and might be acceptable stylistic emphasis. Summary - RevisedAfter careful review of the entire document, I find that most apparently capitalized terms are either: (1) properly capitalized as they derive from proper nouns (Gaussian from Gauss, Markov from Markov, etc.), (2) are standard acronyms (IID, VAR, LSS), or (3) appear in code/math contexts outside the scope of narrative text rules. Issues Found0 Violations37. qe-writing-006 - Capitalize lecture titles properlyLocation: Line 63 / Section "A particular additive functional" Description: This section heading capitalizes "A" which is correct, but the rule requires checking if other words should not be capitalized. However, in this case, all words after "A" are lowercase, so this is actually correct. Let me re-examine the document for actual violations. Explanation: Upon re-examination, this heading is actually correct as written. 38. qe-writing-006 - Capitalize lecture titles properlyLocation: Line 105 / Section "Linear state-space representation" Description: The section heading "Linear state-space representation" correctly capitalizes only the first word and the proper noun would be checked, but "state-space" is a technical term, not a proper noun. This heading is correctly formatted. Explanation: This is correctly formatted per the rule. 39. qe-writing-006 - Capitalize lecture titles properlyLocation: Line 192 / Section "Simulation" Description: Section heading uses title case. Should only capitalize the first word. Explanation: This heading is actually correct - "Simulation" is the first word and is capitalized. No change needed. 40. qe-writing-006 - Capitalize lecture titles properlyLocation: Line 424 / Section "Plotting" Description: Section heading only capitalizes first word, which is correct according to the rule. Explanation: This is correct as written. 41. qe-writing-006 - Capitalize lecture titles properlyLocation: Line 609 / Section "Decomposition" Description: This section heading is correctly formatted with only the first word capitalized. Explanation: Correct as written. 42. qe-writing-006 - Capitalize lecture titles properlyLocation: Line 798 / Section "Associated multiplicative functional" Description: This section heading correctly capitalizes only the first word. Explanation: Correct as written. 43. qe-writing-006 - Capitalize lecture titles properlyLocation: Line 842 / Section "Peculiar large sample property" Description: This section heading correctly follows the rule by capitalizing only the first word. Explanation: Correct as written. 44. qe-writing-006 - Capitalize lecture titles properlyLocation: Line 1092 / Section "Sample paths" Description: This section heading correctly capitalizes only the first word. Explanation: Correct as written. Review ResultsSummaryNo violations found for qe-writing-006. The lecture follows this rule correctly - the main title uses title case capitalization while all section and subsection headings capitalize only the first word and proper nouns. Issues Found0 Violations45. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 110-111 / Section "Overview" Description: Overly long sentence with unnecessary complexity. The sentence exceeds 40 words and contains redundant phrasing that reduces clarity. Explanation: Removes redundant "there are" construction and reduces word count from 29 to 22 words while maintaining meaning. 46. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 125-126 / Section "Overview" Description: Unnecessarily verbose sentence with redundant phrasing. Explanation: "Describe and compute" is redundant when the lecture actually computes them. The computation itself describes the process. 47. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 133-134 / Section "Overview" Description: Unnecessarily verbose phrase. Explanation: Direct statement is clearer than "describe how to." 48. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 156-158 / Section "A particular additive functional" Description: Overly complex sentence structure that could be simplified. Explanation: Removes "special" (subjective) and "while also being" (verbose), making the sentence more direct. 49. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 160 / Section "A particular additive functional" Description: Redundant phrasing. Explanation: "The first of which is" is unnecessarily wordy; a colon is more direct. 50. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 179-183 / Section "A particular additive functional" Description: Overly long sentence with complex structure that reduces clarity. Explanation: Removes "is an equation that" (verbose) and "the same...that appears in the VAR" (redundant, since the equation reference is sufficient). 51. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 197 / Section "A particular additive functional" Description: Redundant phrase. Explanation: "Nonstationary random" is redundant given "systematic but random" later in the sentence; the non-stationarity is implied by growth. 52. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 221-224 / Section "Linear state-space representation" Description: Unnecessarily verbose phrase. Explanation: Combines setup and conclusion into one sentence, eliminating "can be written as...which is." 53. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 226-227 / Section "Linear state-space representation" Description: Verbose construction. Explanation: Removes "To study it" and "an instance of" as unnecessary verbiage. 54. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 229 / Section "Linear state-space representation" Description: Verbose phrase. Explanation: More concise without losing meaning. 55. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 235 / Section "Dynamics" Description: Redundant phrase. Explanation: "Some" adds no value in this context. 56. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 238-239 / Section "Dynamics" Description: Verbose phrasing. Explanation: "In doing so" is unnecessary setup that can be eliminated. 57. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 249-251 / Section "Dynamics" Description: Overly verbose construction with unnecessary words. Explanation: "In which" → "where" and "are strictly greater than" → "exceed" for conciseness. 58. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 253 / Section "Dynamics" Description: Unnecessary parenthetical that states the obvious. Explanation: This is the definition of "zero" and adds no value for the technical audience. 59. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 264-266 / Section "Dynamics" Description: Overly verbose sentence with unnecessary complexity. Explanation: Removes "a...system" (obvious from context) and "we know that" (unnecessary). 60. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 272 / Section "Dynamics" Description: Verbose construction. Explanation: More direct phrasing removes "In fact, this whole" and "definition in...by appropriate selection of." 61. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 274 / Section "Dynamics" Description: Unnecessarily informal and verbose. Explanation: The suggestion to "try writing...as an exercise" is patronizing and unnecessary; just state what's provided. 62. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 278-279 / Section "Simulation" Description: Verbose and unnecessarily complex sentence. Explanation: More direct sentence structure. 63. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 281-282 / Section "Simulation" Description: Overly verbose construction. Explanation: Removes redundant "also" and "proposed by" (citation already attributes). 64. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 284 / Section "Simulation" Description: Unnecessarily verbose phrase. Explanation: More direct construction, active voice. 65. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 554 / Section "Decomposition" Description: Verbose phrase. Explanation: "At this stage, you should pause and" is unnecessary instructional padding. 66. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 565-569 / Section "Decomposition" Description: Overly long sentence that reduces clarity. Explanation: Removes "A convenient way to do this is to" and "an appropriate instance of" for directness. 67. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 575 / Section "Decomposition" Description: Verbose construction. Explanation: "To start, observe that," and "with the definitions just given" are unnecessary setup. 68. qe-writing-002 - Keep writing clear, concise, and valuableLocation: Line 655-658 / Section "Code" Description: Overly long and complex sentence. Explanation: The parenthetical is unnecessarily long and complex. The key information is the acronym; that it computes multiplicative functionals is already stated in the previous sentence. |
🎨 Style Suggestions for Human ReviewLecture: additive_functionals Style improvements are subjective - please review each suggestion carefully. Writing (10 suggestions)1. qe-writing-003 - Maintain logical flowLocation: Line 205-211 / Section "Linear state-space representation" Severity: warning Description: The transition to the linear state space representation section is somewhat abrupt. The lecture jumps from defining the additive functional to suddenly setting up state and observation vectors without explaining why this representation is useful or necessary at this point. Explanation: This addition provides a bridge explaining why we're introducing the state space representation, connecting it to the upcoming analysis needs (dynamics, decomposition, simulation) and making the transition more natural. 2. qe-writing-003 - Maintain logical flowLocation: Line 276-282 / Section "Simulation" Severity: warning Description: The lecture abruptly introduces a "bigger system" for simulation without explaining what makes it bigger or why embedding is necessary. This creates a logical gap between the stated model and what's actually being simulated. Explanation: This revision clarifies what the "bigger system" contains and why we're embedding variables this way, creating a smoother transition to the implementation details. 3. qe-writing-003 - Maintain logical flowLocation: Line 608-620 / Section "Sample paths" Severity: warning Description: After extensive discussion of multiplicative martingales and their properties, the lecture abruptly returns to "Let's write a program to simulate sample paths" as if starting fresh, followed by redefining the Explanation: This revision clarifies that we're presenting a simplified version for a specific purpose (studying the multiplicative martingale distribution), rather than seeming to restart the exposition. It connects back to the previous discussion and explains why we're revisiting the simulation code. 4. qe-writing-007 - Use visual elements to enhance understandingLocation: Line 74-107 / Section "A particular additive functional" Severity: warning Description: This section introduces complex mathematical structures (VAR system and additive functional equations) that would benefit from a visual diagram showing the relationships between components. Explanation: A diagram showing the flow from 5. qe-writing-007 - Use visual elements to enhance understandingLocation: Line 109-150 / Section "Linear state-space representation" Severity: warning Description: The augmented state space representation involves complex matrix constructions that would benefit from a visual representation showing the block structure. Explanation: Adding an admonition highlights the key conceptual insight, and a diagram showing the block structure of the matrices would help readers understand the augmentation strategy more clearly. 6. qe-writing-007 - Use visual elements to enhance understandingLocation: Line 268-303 / Section "Decomposition" Severity: warning Description: The four-way decomposition is a central concept that would greatly benefit from a visual diagram showing how the components relate and combine. Explanation: A diagram showing sample paths of each component and how they sum to produce 7. qe-writing-007 - Use visual elements to enhance understandingLocation: Line 628-638 / Section "Associated multiplicative functional" Severity: warning Description: The relationship between additive and multiplicative functionals through the exponential transformation would benefit from visual illustration. Explanation: Adding an admonition clarifies the conceptual connection, while a side-by-side comparison figure would visually demonstrate how exponential transformation changes the character of growth from arithmetic to geometric. 8. qe-writing-007 - Use visual elements to enhance understandingLocation: Line 681-695 / Section "Peculiar large sample property" Severity: warning Description: This important and counterintuitive property would benefit from an admonition to emphasize its significance. Explanation: This is a key conceptual insight that is counterintuitive and important. An "important" admonition box would draw appropriate attention to this result and help readers recognize its significance. 9. qe-writing-007 - Use visual elements to enhance understandingLocation: Line 707-717 / Section "More about the multiplicative martingale" Severity: warning Description: The log-normal distribution property could be highlighted with an admonition for emphasis. Explanation: Using an admonition highlights this distributional result and adds a brief interpretive comment that helps readers understand the implications of linear growth in both mean and variance. 10. qe-writing-007 - Use visual elements to enhance understandingLocation: Line 1044-1069 / Section "Multiplicative martingale as likelihood ratio process" Severity: info Description: This short but conceptually important section connecting to likelihood ratios could benefit from a more prominent visual treatment or admonition. Explanation: Using a "seealso" admonition elevates this important conceptual connection and provides more context about why this connection matters, encouraging readers to explore the related lecture with better understanding of the relationship. |
