Dear Stata Users,

Please, help me with the following.

How do I compare statistical difference between coefficients of two regressions below:

Code:
areg y B_1*x_1 x_2 x_3 if group==1, ab(industry) vce(cluster industry)
areg y B_1*x_1 x_2 x_3 if group==2, ab(industry) vce(cluster industry)
Since, “suest” does not allow for “areg” and clustering, what I tried is as follows:
Code:
reg y B_1*x_1 x_2 x_3 i.industry if group==1
est store group1
reg y B_1*x_1 x_2 x_3 i.industry if group==2
est store group2
 
suest group1 group2, vce(cluster industry)
test [group1 _mean]x_1=[group1 _mean]x_1
But it did not work due to inclusion of industry fixed effect (i.industry). Is there any way how to deal with this?
