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 101, line 165. Count: 15 occurrences across 9 lines.

  • [qe-fig-006] — Axis labels capitalised in 14 places (should be lowercase). Examples: line 270, line 271, line 327.

Medium severity#

  • [qe-writing-009 (proposed)] — Uses “i.i.d.” or “iid” in text rather than “IID”. Example: line 137. Count: 2

Low severity#

  • [qe-writing-006] — One section heading uses Title Case. Example: line 449 $\chi^2$ Distribution.

  • [qe-math-012 (proposed)] — Multiplication with * rather than \cdot or juxtaposition. Example: line 285.

  • [qe-code-002] — Greek letters spelled out in code; consider unicode forms. Count: 5.

  • [qe-fig-001] — figsize= set in 7 places — usually unnecessary.

  • [qe-fig-003] — ax.set_title() used once outside exercise blocks (line 445).

  • [qe-fig-005] — Figures lack descriptive name: fields for cross-referencing (9 plot calls, 0 named).

  • [qe-fig-008] — lw=2 parameter missing from 9 .plot() calls.

  • [qe-link-001] — 1 full URL(s) to same series. Examples: line 16.

Strengths#

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

  • Normal distribution written as plain N.

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