Hi, I am fitting the generalized gamma distribution to survival data.I need all three parameters of generalized gamma to have linear relationship with covariates without having the intercept.The command "streg[varlist],dist(gamma) anc(varlist) anc2(varlist) noconstant" only model the first parameter without intercept, and would not remove the constant terms in two ancillary parameters. What can I do to suppress the constant terms in two ancillary parameters('anc' and 'anc2')?
