老师您好,按照您的代码,我输入之后,其他两个自变量都能画出来图,只有rd这个自变量画不出来,还出现一串问题,烦请您帮忙看看。
reg inv rd c.rd#c.rd ee es te, robust
Linear regression Number of obs = 869
F(5, 863) = 151.53
Prob > F = 0.0000
R-squared = 0.4007
Root MSE = 1.8722

. marginscontplot2 rd, ci
There was a problem executing -margins-.
The command issued was essentially as follows:
margins , at( rd=( 9.210340371976 10.25179412916 10.28813684024 10.6919449129 10.81977828441。。。
