我在做面板数据的截面相关性检验时,首先输入命令: ssc install xtcsd结果显示checking xtcsd consistency and verifying not already installed...all files already exist and are up to date.我再用xtcsd,pes时他又显示time variable not set, use -tsset varname ...-我用tsset year(我用的时间变量是以年为单位的),他却显示repeated time values in sample,对此我很是茫然又无语,请问有哪位大侠可以不吝赐教,帮帮我呢,先谢谢了哈。
lz怎么解决这个问题 “首先输入命令: ssc install xtcsd结果显示checking xtcsd consistency and verifying not already installed...all files already exist and are up to date.”
是不是命令名字改变了,这个要怎么找?
