Dear Stata Experts,
I encountered a simple command to export my table using outreg but I am lost on how to specify in the dummy variable I need to drop.
Let me show you the codes and stata result.
[CODE]
xtreg InpatientNo i.Agegroup_new i.Country_new Agegroup_new##Country_new, re robust
Random-effects GLS regression Number of obs = 19,352
Group variable: panelid Number of groups = 7,068
R-squared: Obs per group:

Wald chi2(7) = 354.73
corr(u_i, X) = 0 (assumed) Prob > chi2 = 0.0000
(Std. err. adjusted for 7,068 clusters in panelid)

Panel Data Regression Random Effects
Robust standard errors in parentheses
*** p<0.01, ** p<0.05, * p<0.1
In this case, The base country for the interaction dummy variable Agegroup_new##Country_new is Finland with 0 coefficients. The variables 1b.Agegroup_new#1b.Country_new, 1b.Agegroup_new#2o.Country_new, 2o.Agegroup_new#1b.Country_new, 3o.Agegroup_new#1b.Country_new, 4o.Agegroup_new#1b.Country_new have to be drop using outreg2 command but I couldn`t find the right way to drop these. I also use the words shown on the table to be dropped but no effect. Can someone help me?
Kind Regards,
