[action-translation] resync: wald_friedman.md

[mmcky]

Forward Resync: wald_friedman.md

Source: QuantEcon/lecture-python.myst — lectures/wald_friedman.md
Source commit: 709deec
This PR resyncs the translation to match the current source document.

Reason: The target includes extra font-configuration code (matplotlib font setup with FONTPATH and Source Han Serif SC) not present in the source's import block. Otherwise the translation is faithful and complete, with only minor phrasing/formatting differences (I18N_ONLY elsewhere).

Changes

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

📝 Translation Quality

Criterion	Score
Accuracy	8/10
Fluency	8/10
Terminology	8/10
Formatting	9/10
Overall	8.2/10

Summary: 整体翻译质量较高，准确传达了原文关于Wald序贯分析理论的核心概念和数学推导，专业术语使用规范，格式保留完整无语法错误。主要问题在于人名翻译（Wald vs 瓦尔德）存在不一致，以及个别长句可以进一步精简以提升流畅度。代码部分新增的中文字体配置代码是合理的本地化适配，不影响翻译质量评估。 长篇统计学术语（如'第一类错误'、'第二类错误'、'检验效能'、'临界区域'、'序贯概率比检验'等）翻译准确且符合术语表要求 复杂的Wald引文段落翻译保持了原文的逻辑结构和学术严谨性，长句拆分恰当，可读性良好 代码块、数学公式（LaTeX）、MyST指令块等格式均完整保留，未出现语法错误 章节标题与YAML frontmatter中的heading映射基本对应良好，有利于跨语言章节匹配

Suggestions:

• 翻译中出现了两次'compute_wald_thresholds'函数定义(在'Now we can run...'部分和':tags: [hide-input]'代码块中)，与英文原文重复结构一致，但第二个定义块中的注释翻译为中文'计算 Wald 推荐的阈值'与第一次'计算Wald推荐的阈值'标点风格不一致（有无空格），建议统一全角/半角空格使用规范
• 'Overview'部分：'第一类和第二类统计错误' 列表下的两个子项翻译为'第一类错误是指在原假设为真时拒绝原假设'和'第二类错误是指在原假设为假时接受原假设'，准确且清晰，但注意与后文'第一类错误'和'第二类错误'章节标题的翻译需保持一致（已一致，无需改动）
• 'Simulations'部分中步骤3的翻译对原文'with N/2 replications for each distribution'的处理为'对每个分布重复步骤2进行N/2次重复，总共N次重复'，虽然基本准确但稍显冗余，可简化为'对每个分布各重复N/2次（共N次），计算经验第一类错误...'以提高流畅度
• 代码块中新增了字体设置代码（FONTPATH, mpl.font_manager等），这些在原始英文源文档的代码块中不存在；虽然这可能是为了支持中文渲染而添加的合理修改，但建议在评审说明中标注这是有意为之的本地化适配，以免被误认为是翻译错误
• '瓦尔德的序贯表述'章节中，将'Wald's sequential formulation'翻译为标题'瓦尔德的序贯表述'，但正文中及其他地方多译为'Wald'（不译或译为'Wald'），存在'瓦尔德'与'Wald'两种译法交替出现的现象（如'瓦尔德定义'与后文'Wald定义'），建议统一全篇对该人名的翻译方式
