http://www.dxy.cn/bbs/thread/35150213#35150213步骤：
1.计算机接入网
2.运行stata12或13
3.在command窗口运行
net from
http://www.stata-press.com/data/maisnet install mais
4.运行
spinst_mais
5.运行
ssc install metadialog.pkg
6.选择“windows”对话框， do-file editor，制作“profile.do”(我已经制作好了，但是无法上传，因此将以下复制进去)，另存为stata主文件夹；
7.重新打开stata，系统自动运行profile.do文件，后面“user”对话框中出现meta-analysis选项。
profile.do内容：
if _caller() >= 8 {
window menu clear
window menu append submenu "stUser" "&Meta-Analysis"
