[action-translation] resync: likelihood_ratio_process.md

Forward Resync: likelihood_ratio_process.md

Source: QuantEcon/lecture-python.myst — lectures/likelihood_ratio_process.md
Source commit: a896696
This PR resyncs the translation to match the current source document.

Reason: Mostly faithful translation with added font-setup code (i18n-only) but one substantive citation error: the source cites {cite}Blume_Easley2006 while the target cites {cite}blume2006if, a changed/different reference key. Also minor garbled text ('本质 = f' instead of 'nature = f' in a plot title), which is a content degradation from mistranslation. These are small but represent actual content changes rather than pure style differences.

Changes

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

Pull request overview

This PR forward-resyncs the Chinese translation of likelihood_ratio_process.md against the upstream QuantEcon source at commit a896696, aiming to keep the translated lecture aligned with the canonical content.

Changes:

• Added per-document translation: metadata (title + heading mappings) to the MyST/Jupytext YAML front matter.
• Fixed a MyST cross-reference formatting issue for {doc} links in the “divergence measures” section.
• Updated a citation key in “Related lectures” and tidied the closing fence for a {solution-end} block.

✅ Translation Quality Review

📝 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 complex statistical and mathematical concepts (likelihood ratio processes, hypothesis testing, KL divergence, Markov chains) with consistent terminology and well-preserved formatting. Minor issues include an unexplained addition of font-configuration code not in the source, one clear mistranslation ('本质' for 'nature' in the Markov chain plot title), and a couple of small consistency/fluency nitpicks. No critical markdown/MyST syntax errors were found. Accurate and consistent rendering of technical terminology (likelihood ratio process, KL divergence, Chernoff entropy, Type I/II errors, ROC curve) throughout the long document Mathematical notation and LaTeX equations preserved correctly across all sections Code blocks, MyST directives, and cross-references (doc, ref, eq, cite) are all intact and correctly formatted Comments within code cells were thoughtfully translated to Chinese, improving readability for the target audience while preserving code functionality The YAML translation metadata block properly maps section headings for cross-language navigation, following the expected convention

Suggestions:

• Code cell font-loading block: The translation adds matplotlib font configuration code (FONTPATH, mpl.font_manager, plt.rcParams) not present in the English source. This is likely intentional for CJK font rendering but should be verified as consistent with the project's standard practice for other translated lectures, since it constitutes an addition beyond a pure translation.
• 'Markov chain likelihood ratios (nature = f)' translated as '马尔可夫链似然比(本质 = f)': '本质' (meaning 'essence/nature' in the philosophical sense) is a mistranslation of 'nature' used here in the sense of 'nature/the world generating the data' (自然). Should be '自然 = f' to match the consistent usage of '自然' elsewhere in the document (e.g., '自然从链f中采样').
• Section 'A third distribution h' - '让我们研究当 $h$ 支配数据时,累积似然比 $L$ 的表现' reads slightly awkwardly; consider '让我们研究当数据由 $h$ 生成时,累积似然比 $L$ 的表现' for smoother flow, though current version is acceptable.
• In '为简便起见,我们有时会写作 $L_t = L(w^t)$' vs later '为简便起见,我们将写作 $L_t = L(w^t)$' — minor inconsistency between '有时会写作' and '将写作' for the same 'For shorthand we'll write' phrase; consider unifying wording for consistency.

Overall	10/10

Summary: The whole-file resync correctly added the translation frontmatter metadata with title and headings map matching the source's heading structure, and the document content/order remains aligned with the English source.

Issues:

• The target 'Before' contained a leftover/stray code fragment 'import matplotlib.pyplot as plt\nFONTPATH = ...\nmpl.font_manager...' missing 'import matplotlib as mpl' - this was fixed in 'After' by adding 'import matplotlib as mpl', which is a reasonable correction consistent with source content, though it's an addition not present in the English source (minor content deviation, but harmless/beneficial).
