求大神帮忙看看，初学STATA，这是作业

import excel "E:\第一学期课程\高级计量经济学\Problem Set\Assignment 2\consumption - 1.xlsx", sheet("Sheet1")

. rename A ob

. rename B year

. rename C quarter

. rename D YD

. rename E CE

. tsset ob
        time variable:  ob, 1 to 176
                delta:  1 unit

. nl (CE = {b0} + {b1}*l.CE + {b2}*YD+ {b3}*l.YD) initial(b0 0.063936 b1 0.969225 b2 0.290988 b3 -0.265151)
varlist not allowed
r(101);

end of do-file

r(101);


哦对了，它之前还报错starting values invalid or some RHS variables have missing values
