✅ Translation Quality ReviewVerdict: PASS | Model: claude-sonnet-5 | Date: 2026-08-03 📝 Translation Quality
Summary: 翻译整体质量很高，准确传达了原文关于观测分布可视化与描述统计的技术内容，术语使用规范，格式保留完整。仅存在个别措辞可进一步打磨之处（如'箱须图'的引入可能造成与'箱线图'的术语不一致，以及个别口语化表达），但不影响理解和整体质量。 统计术语（样本矩、样本分位数、核密度估计、经验累积分布函数等）翻译准确且与术语表高度一致 长句拆分处理得当，保持了学术文本的严谨性和可读性 数学公式、代码块和MyST指令格式完整保留，无语法错误 Suggestions:

- 小提琴图的 x 轴被标注为“KDE”，但该图展示的是 violin plot（并非 KDE 曲线），该标签会误导读者。建议移除该 x 轴标签或改为更贴切的含义。
ax.violinplot(x_amazon)
ax.set_ylabel('monthly return (percent change)')
ax.set_xlabel('KDE')

- 此处将 x_amazon / x_costco 当作带股票代码列的对象来索引（['AMZN'] / ['COST']），但上文它们被当作一维样本使用（例如 x_amazon.mean()、scipy.stats.norm(μ, σ) 等都假定 μ、σ 为标量）。为避免类型不一致/潜在 KeyError，建议直接传入这两个样本序列。
ax.violinplot([x_amazon['AMZN'], x_costco['COST']])

Closing as superseded by #283. All three of #278, #281 and #283 add
#278 has now merged, so the lecture exists on Merging both would mean resolving the same new-file conflict twice for a strictly older result. The captions land via #283, which is queued after #279 ( |
