Forward Resync: likelihood_ratio_process_2.md

Source: QuantEcon/lecture-python.mystlectures/likelihood_ratio_process_2.md
Source commit: a896696
This PR resyncs the translation to match the current source document.

Reason: The Chinese translation omits several substantive parts of the source: the note about {cite}blume2018case is truncated (missing the sentence about replacing beliefs with the planner's beliefs about probabilities); the 'If you're so smart' section is missing the note's bullet-point intro sentence and loses some paragraph breaks with headers turned into inline math statements; also a font-loading code snippet (mpl.font_manager...) is added in the target's import cell which is i18n-related but otherwise fine. More importantly, citation key differs: source uses {cite}Blume_Easley2006 while target uses `{cite}`blume2006if (a factual/reference change). Several explanatory sentences are shortened or dropped (e.g., detail about welfare theorem discussion, and the concluding paragraph in blume2018case discussion). These are content omissions requiring re-translation.

Changes

Whole-file resync applied. The entire document was resynced in a single pass.

The resynced file keeps Chinese plot labels but reverted the import
cell to the source's exact form, losing the Source Han Serif setup -
Chinese in figures would render as missing glyphs. Residual #107
class found in the merge review; applied wave-wide.

✅ Translation Quality Review

Verdict: PASS | Model: claude-sonnet-5 | Date: 2026-07-19


📝 Translation Quality

Criterion Score
Accuracy 9/10
Fluency 9/10
Terminology 9/10
Formatting 8/10
Overall 8.9/10

Summary: This is a high-quality, comprehensive translation that accurately conveys the complex economic and mathematical content of the source document. Terminology is largely consistent with the provided glossary, formatting (equations, code blocks, directives) is well preserved, and the prose reads naturally in academic Simplified Chinese. Minor issues include one instance of 'numeraire' translated differently from the glossary's preferred term, and an unexplained addition of font-loading code not present in the source (likely a project-wide localization convention rather than a translation error). No critical syntax errors were found. Faithful and precise rendering of complex mathematical derivations and equations, with LaTeX formatting fully preserved Consistent and accurate translation of specialized economic terms (帕累托权重, 竞争均衡, 似然比过程) matching the reference glossary Code blocks, exercise/solution directive structures, and cross-references are all correctly preserved Comments within code cells are appropriately translated into Chinese, improving readability for the target audience Long technical passages (e.g., on welfare theorems, Bayesian updating, KL divergence) are translated clearly and read naturally in academic Chinese

Suggestions:

  • Code cell after 'Python工具' import: The translation adds font-loading code (FONTPATH, mpl.font_manager, plt.rcParams) not present in the English source's code cell — this is an addition beyond translation scope and should be verified against project convention, though it may be a standard localization pattern for CJK font rendering
  • Section '如果你这么聪明': The English phrase 'let's suppose that' is translated inconsistently as '让我们假设' in some places and '让我们假设' elsewhere — consistent, but double-check parallel phrasing across the three cases (first, second, third) matches structure exactly
  • In '竞争均衡价格' section: 'p_t(s^t)' explanation paragraph — the phrase 'These values are computed at price vectors that the agents take as given' is translated as '这些价值是根据个体视为既定的价格向量计算的' which is accurate but slightly reorders emphasis; consider '这些价值是按照个体视为既定的价格向量来计算的' for smoother flow
  • Minor terminology check: 'numeraire' is translated as '计价单位' in one instance and '计价商品' is the glossary term — for consistency with the glossary, consider using '计价商品' instead of '计价单位' where 'numeraire' appears in the Competitive equilibrium prices section

Summary: The resync correctly added the translation metadata block, fixed the citation key, restored a missing import line, and preserved document structure and section positions matching the source.

The resync of likelihood_ratio_process_2.md pulled in {cite}`Blume_Easley2006`
from upstream, but the shared quant-econ.bib was not synced, so the strict
build (-W) failed on "could not find bibtex key". Entry copied verbatim from
QuantEcon/lecture-python.myst.

All four bibtex keys the wave needs (Lucas_Prescott_1971, Blume_Easley2006,
MaCurdy1982, Meghir2004) are now present identically across the affected
branches so the resync PRs merge without append-at-EOF conflicts. Entries
