求助!!!求各位大神搭救
stata怎么才能把mi set 模式改成面板数据,因为之前用了一个口令如下:
//修整数据把ln返回
gen TFP=cpxssr
mi set wide
mi register passive TFP
qui mi passive:replace TFP=exp(lnTFP)
order cpxssr TFP lnTFP
gen LP=VA/qbzg
mi set wide
mi register passive LP
qui mi passive:replace LP=exp(lnLP)
order now frdm frdm_123 hylb lnTFP lnLP age size1 x indus_size hhi4 jrl1 jrl2 ckqd
save "G:\论文数据\1\转换后数据\原始数据转换后\数据整理1.dta",replace
就是之前用过 mi set 这个命令,现在我要求TFP的滞后期变量必须用面板数据可是现在它出现一大段红色字体如下:
no; data are mi set
Use mi tsset to set or query these data; mi tsset has the same syntax as tsset.
Perhaps you did not type tsset. Some commands call tsset to obtain information about the settings. In that case,
that command is not appropriate for running directly on mi data. Use mi extract to select the data on which you want
to run the command, which is probably m=0.
咋办啊???
