Sentence-case headings; clean one-sentence paragraphs.

Math

8/10

\mathbf 1 for indicator (qe-math-008 spirit).

Code

6/10

Spelled Greek (alpha, beta, etc.) used heavily (17 occurrences); install cell with hide-output.

JAX

N/A

not a JAX lecture

Figures

7/10

5 figsize=; no :name: fields; one {only} latex directive present (good for plotly-ish placeholder).

References

8/10

15 {cite} consistently used; never uses {cite:t}.

Links

7/10

One raw python-programming.quantecon.org URL (L874); one raw python-intro.quantecon.org URL (L50).

Admonitions

N/A

no exercises, solutions, or proof-family directives.

Issues#

Critical#

None found.

High severity#

None found.

Medium severity#

  • [qe-link-002] — Raw cross-series URLs instead of {doc}. Example: lectures/arma.md:50 (python-intro.quantecon.org/linear_models.html), :874 (python-programming.quantecon.org/python_advanced_features.html#descriptors). Count: 2 occurrences.

  • [qe-code-002] — Spelled-out Greek (alpha, beta, phi, theta) in code parameters instead of unicode (17 occurrences across code cells).

Low severity#

  • [qe-math-008] — \mathbf 1\{k = 0\} used for the indicator function. Example: lectures/arma.md:134, :136. Count: 2 occurrences.

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

  • [qe-fig-001] — figsize= set 5 times.

  • [qe-ref-001] — {cite:t} never used; some narrative refs (e.g. “Sargent 1987”) would benefit.

Strengths#

  • Title uses Title Case via {index} directive (qe-writing-006).

  • Sentence-case subheadings (qe-writing-006).

  • Sequences in curly brackets \{X_t\} (qe-math-005).

  • \mathbb Z, \mathbb R notation correct.

  • One-sentence paragraph rule respected (qe-writing-001).

  • Install cell at top with hide-output (qe-code-003).
