我是stat13.1，怎么安装此命令呢？

你好 我也是出现了这个情况 请问你是怎么解决的和安装xtabond的呢

cannot write in directory view dialog import_excel_dlg:\stata13\ado\plus\x
这是什么情况？请赐教。

本人刚刚会的，不确定此方法是否适用于所有的stata版本：
    如果输入ssc install xtabond2显示没有安装成功的话，可以通过findit命令需找相关程序的网站，
：具体步骤是
首先，输入findit xtabond2，stata软件会显示此界面：

我不太确定是否每个stata的版本都适用此办法，本人也是刚刚学，有什么不对的，希望大家指点

请问是直接打开连接下载第一个就行了吗？为什么我点下载之后会打开一个都是代码的页面呢

我用楼上的方法还是出现“checking st0159 consistency and verifying not already installed...
connection timed out -- see help r(2) for troubleshooting
