Score breakdown#

Category

Score

One-line note

Writing

8/10

Title in Title Case; sentence-case headings; some longer paragraphs.

Math

7/10

Mixed \mathbb{1} / \mathbf{1}; primes are next-period notation, not transpose.

Code

6/10

9 spelled Greek; no install cell (uses scipy/networkx — networkx not in Anaconda).

JAX

N/A

not a JAX lecture

Figures

3/10

27 figsize= settings; 2 spines.set_visible(False); no :name: fields.

References

8/10

10 {cite} used; never {cite:t}.

Links

7/10

Two raw python.quantecon.org/intro.quantecon.org URLs.

Admonitions

N/A

no exercises, solutions, or proof-family directives.

Issues#

Critical#

None found.

High severity#

  • [qe-fig-001] — figsize= set 27 times — systemic. Count: 27 occurrences.

  • [qe-fig-007] — ax.spines[...].set_visible(False) used (2 occurrences) — should keep default box.

Medium severity#

  • [qe-math-008] — Inconsistent indicator notation: \mathbb{1} (L222) and \mathbf{1}_N (L525). Should use \mathbb{1} consistently. Count: 1 \mathbf{1} occurrence.

  • [qe-link-002] — Two raw cross-series URLs (python.quantecon.org/opt_transport.html, intro.quantecon.org/lp_intro.html). Example: lectures/match_transport.md:40, :44. Count: 2 occurrences.

  • [qe-code-006] — networkx is not in Anaconda; missing install cell.

  • [qe-code-002] — 9 spelled Greek (alpha, gamma) in code.

Low severity#

  • [qe-writing-005] — Heavy bold for **positive assortative**, **negative assortative**, etc.; some definitional, some emphasis.

  • The many primes (x', y') are primed variable names, not transpose — no qe-math-002 violation.

  • [qe-fig-005] — Figures lack :name: fig-... fields.

Strengths#

  • Title “Composite Sorting” in Title Case (qe-writing-006).

  • Subheadings sentence case (qe-writing-006).

  • \begin{bmatrix} used where matrices appear (qe-math-003).

  • Sequences \{ ... \} (qe-math-005).

  • \mathbb{R}, \mathbb{Z}_+ correctly used.

  • Equation labels and {eq} references (qe-math-007).
