重复贴！有版友反映，我通过论坛电信通道（https://bbs.pinggu.org/thread-325915-1-1.html）上传的该文档部分教育网用户无法下载，特重新上传！

A Must Read for Stata Programming!

论坛上有此文档的word版本，但格式很乱，而且没有相应链接，使用起来很不方便。现忙里偷闲将其处理成pdf版本，创建了全部链接，并重排版面尽可能使其美观，看起来舒服；同时添加了全部数据和程序文档。

低价有偿分享，希望看过用过觉得好的朋友顶一个，让更多人享有好东西。

引用作者的话“The (Stata programming) manual does a good job of detailing what particular commands do; it does not show how the features work together, and that is what I have tried to focus on...I hope I have communicated the grammar of Stata and not just the vocabulary.”
