I am new is Stata modelling.
I am running the following model:
by n:gammafit y, level(95)
pgamma y, gen(g_p e_p)
where n is a group variable.
I would like to save the estimated parameters by gammafit (alpha,beta,alpha+beta
and lower and upper limit of both alpha and beta) in a variable 'result(n,j).'
Also, I would like pgamma to estimate the probabilities (g_p and e_p) by
variable n.
The pgamma module does not accept the 'by' option. In addition, is there a way
to give starting values for the gammafit module?
