Issues#

Critical#

None found.

High severity#

  • [qe-math-004] — Vectors/matrices typeset with \mathbf or \boldsymbol (style guide says no bold for vectors). Examples: line 606, line 650. Count: 11 occurrences across 9 lines.

  • [qe-math-010 (proposed)] — Bare E[...], \Pr(...), or \Var(...) used instead of \mathbb{E}, \mathbb{P}, \mathbb{V}. Examples: lines 2266, 2269. Count: 20 chunks.

Medium severity#

  • [qe-math-008] — Ones vector typeset with \mathbf{1} rather than \mathbb{1}. Examples: line 650. Count: 6 occurrences.

  • [qe-writing-009 (proposed)] — Uses “i.i.d.” or “iid” in text rather than “IID”. Examples: lines 602, 1830. Count: 3 occurrences.

Low severity#

  • [qe-writing-006] — One section heading uses Title Case. Example: line 1389 Constructing a Wold representation.

  • [qe-code-002] — Mixed Greek conventions in code (word=19, uni=26).

  • [qe-fig-001] — figsize= set in 2 place(s).

  • [qe-fig-008] — lw=2 missing on most .plot() calls (1/15).

Strengths#

  • Transpose notation uses \top consistently (no prime/^T).

  • Normal distribution written as plain N.

  • aligned (not align) used in $$ math.

  • Solutions use :class: dropdown consistently.

  • No ax.set_title() in main figures.

  • Axis labels lowercase.

  • No embedded matplotlib titles in main figures.
