stata外部命令：那些最常用的和最新的命令

导读：

stata中最重要的两个命令莫过于help和search了。即使是经常使用stata的人也很难，也没必要记住常用命令的每一个细节，更不用说那些不常用到的了。help和search都是查找帮助文件的命令，它们之间的区别在于help用于查找精确的命令名，而search是模糊查找。本文将为大家梳理出最新的外部命令和最热门外部命令，并且提供完整讲解。

－ stata －

最流行的Stata 非官方命令下载平台为“统计软件成分”(Statistical Software Components，SSC)，由 Boston College 维护，网址为 http://ideas.repec.org/s/boc/bocode.html。

想知道，现在的热点命令是什么吗？

ssc hot查看热点命令

ssc new   (罗列 SSC 的最新非官方Stata 命令及简介) 

ssc hot   (罗列 SSC 提供的最流行非官方 Stata 命令) 

ssc install newcommand   (安装 SSC 非官方命令“newcommand”)

help ssc   (有关 SSC 的帮助信息) 

获取外部命令的最佳方式是使用 - findit - 命令，在搜索完成后，可以按照 stata 的提示直接下载安装相应的命令和作者提供的范例数据或dofiles(如果有的话)。

另外，也可以help加命令来查看自己该外部命令是否已经正确安装，若是已经安装，则显示完整的帮助文件。

ssc hot

输入ssc hot, n(30)，可以得到过去最火热的30个命令，如下：
