Score breakdown

Category	Score	One-line note
Writing	7/10	Uses “i.i.d.” or “iid” in text rather than “IID”.
Math	9.5/10	Bare E[...] or \Pr(...) used in place of \mathbb{E}/\mathbb{P}.
Code	8.5/10	Spelled-out Greek (alpha/beta/etc.) used predominantly in code; mixed with unicode forms…
JAX	out of scope	not a JAX lecture
Figures	6/10	figsize= set in 8 places — usually unnecessary.
References	N/A	No citations.
Links	10/10	Link style follows conventions.
Admonitions	10/10	Exercise/solution structure clean.

Issues

Critical

None found.

High severity

• [qe-fig-003] — ax.set_title() / fig.suptitle() used 7 times outside exercise blocks. Examples: line 243, line 276, line 308.

Medium severity

• [qe-writing-009 (proposed)] — Uses “i.i.d.” or “iid” in text rather than “IID”. Examples: lines 22, 325. Count: 3 occurrences.

• [qe-writing-006] — Section headings use Title Case rather than sentence case. Examples: line 72 Frequentist Interpretation, line 340 Bayesian Interpretation. Count: 3.

• [qe-code-002] — Spelled-out Greek (alpha/beta/etc.) used predominantly in code; mixed with unicode forms (word=15, uni=4).

• [qe-fig-006] — Axis labels capitalised in 4 places. Examples: line 559, line 616, line 622.

Low severity

• [qe-math-010 (proposed)] — Bare E[...] or \Pr(...) used in place of \mathbb{E}/\mathbb{P}. Example: line 333.

• [qe-fig-001] — figsize= set in 8 places — usually unnecessary.

• [qe-fig-005] — Figures lack descriptive name: fields for cross-referencing (10 plot calls, 0 named).

• [qe-fig-008] — lw=2 parameter missing from 10 .plot() calls.

Strengths

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

• No bold vectors/matrices.

• Normal distribution written as plain N.

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

• Solutions use :class: dropdown consistently.
