Hi,
I have ran a regression with interaction variables as shown below and received the output where δ1=0.179, δ2=-0.046, δ3=-0.118 and δ4=-0.158. I would like to add the coefficients (which can be done manually). However, how do I go about adding the clustered standard errors? Is there any function/command in Stata which adds up the coefficients and standard errors? I do know that lincom can be used. However, what about for multiple regressions (controlling for different variables) which requires the addition of the same coefficients as well?


Thank you.
