HI all,

I'd like to use deviation coding and to have all the coefficients for each
categorical variable sum to zero.
Right now I'm using xi3 deviation & lincom
xi3: regress y e.x1 e.x2
Lincom -_Ix1_2-_Ix1_3-_Ix1_4 (for x1=1)
Lincom -_Ix2_2-_Ix2_3-_Ix2_4 (for x2=1)
Lincom _cons+_Ix1+...._Ix2_4 for the new constant

Is it a more convenient way to achieve this?

Thanks for your help
