Score breakdown

Category	Score	One-line note
Writing	8/10	“i.i.d.” used instead of “IID”.
Math	5/10	Normal distribution written with \mathcal{N} rather than plain N.
Code	9.5/10	Mixed Greek conventions in code (word=7, uni=10).
JAX	out of scope	not a JAX lecture
Figures	8/10	figsize= set in 5 places — usually unnecessary.
References	9/10	Citation style follows conventions.
Links	10/10	Link style follows conventions.
Admonitions	10/10	Exercise/solution structure clean.

Issues

Critical

None found.

High severity

• [qe-math-011 (proposed)] — Normal distribution written with \mathcal{N} rather than plain N. Examples: lines 110, 222, 231, 234, 331, 454, 1041, 1049, 1073, 1083. Count: 11 occurrences.

• [qe-fig-006] — Axis labels capitalised in 15 places (should be lowercase). Examples: line 610, line 611, line 620.

Medium severity

• [qe-math-003] — Matrices use \begin{pmatrix} rather than \begin{bmatrix}. Examples: line 731, line 1303. Count: 2 occurrences.

• [qe-writing-009 (proposed)] — “i.i.d.” used instead of “IID”. Example: line 110 is an i.i.d. $m \times 1$ random vector.

Low severity

• [qe-writing-001] — A handful of multi-sentence paragraphs (e.g. line 53–54) that could be broken into one-sentence units.

• [qe-code-002] — Mixed Greek conventions in code (word=7, uni=10).

• [qe-fig-001] — figsize= set in 5 places — usually unnecessary.

Strengths

• Consistent use of ^\top for transpose throughout (~95 instances).

• Equations use the recommended \begin{math} :label: form.

• Probability and expectation use \mathbb{P}, \mathbb{E} correctly.

• Solutions use :class: dropdown consistently.

• No ax.set_title() in main figures.

• Figures use descriptive name: fields for cross-referencing.
