这个问题是论坛上的老问题了。

time variable必须是数值型变量，且取值是整数。

（简单说，time variable必须可以充当stata中的"date and time"）

函数int()

或者重新生成一组整数：

egen tt=group(t)

asher314 发表于 2011-5-8 13:03 输入 tsset year province ，怎么显示repeated time values within panel

*首先，命令格式是：

tsset panelvar timevar

*其次，panel data中，当panelvar相同时，timevar不能再有相同值。

简单说，变量组(province, year)不能有重复值。

tsset panelvar timevar

是说直接把tsset panelvar timevar输入就可以了吗？还是需要根据自己的需要进行改变？

tsset后面第一个变量标识单位，第二个变量标识时间。

是不是因为tsset 命令是先定义截面变量，再定义时间变量，你把顺序弄反了
本人也是刚刚学习面板数据，不甚了解，希望能帮到你

我运用了正确的命令，但还是显示时间变量重复，请问怎么克服？我核对多次仍未发现，劳驾

sort id time
egen p=tag(id time)

*看看p有无0值
