📝 Translation Quality

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

Summary: The 'Likelihood implementation' section is translated accurately and fluently, with correct handling of technical terminology (likelihood, residuals, covariance matrix, Jacobian, OPG standard errors, etc.) and full preservation of code blocks, math, and MyST formatting. No syntax errors or accuracy issues were found; only very minor stylistic nits could be considered for further polish. The dense mathematical/statistical prose in the 'Likelihood implementation' section is translated with precise and consistent terminology (对数似然、残差、协方差矩阵、雅可比 etc.), matching the glossary and prior sections. All code comments and docstrings within the changed section are fully and accurately translated while preserving code structure and functionality. Math notation, equation labels, and MyST cross-references (e.g., {eq}hs83-loglik) are preserved exactly as in the source, with correct spacing around inline directives per the language policy.

Suggestions:

• [minor · terminology] lectures/hansen_singleton_1983.md — ## 似然的实现 / '组成部分有：' list: The English phrase 'the Gaussian log-likelihood itself' is translated as '高斯对数似然本身', which is fine, but the parallel structure of the bullet list ('a function to..., a function to..., a function to..., and the Gaussian log-likelihood itself') is slightly weakened because the fourth item doesn't start with '一个函数' like an implied parallel item, though this is a minor stylistic issue not an error. → No change strictly required; optional: '以及高斯对数似然函数本身' for closer parallelism.
• [nit · fluency] lectures/hansen_singleton_1983.md — ## 似然的实现, comment '# 来自无限制 VAR 的 OLS 种子': Code comment translation reads naturally but could be tightened; 'OLS 种子' is a literal but acceptable rendering of 'OLS seed', consistent with usage elsewhere in the document.

Summary: The translation sync correctly mirrors the source's np.random.default_rng refactor and blank-line removal, with no scope or structural issues, aside from one minor unrelated wording tweak.

Issues:

• A sentence near 'residual_diagnostics' function definition was reworded in the target ('残差诊断下面总结了...' vs '下面的残差诊断总结了...') in a way that doesn't clearly correspond to a source change and reads less naturally in Chinese, though it doesn't affect structure or scope.

Pull request overview

This PR syncs the zh-cn translation of hansen_singleton_1983.md with upstream changes that migrate NumPy RNG usage from the legacy global np.random API to the Generator (default_rng) API, and updates the translation sync state metadata accordingly.

Changes:

• Updated the lecture’s simulation code to use rng = np.random.default_rng(seed) and rng.multivariate_normal(...) instead of the global np.random state.
• Minor markdown text/whitespace adjustments in the lecture content.
• Updated .translate/state/hansen_singleton_1983.md.yml to reflect the new source SHA, model, sync date, and tool version.
