Re: predict probability and CI

Hi George, I just manage to get s.e. just by copying or replacing original vars with a set of vars_1 and vars_2 which the stata recognises. The commands are like these (response 0: reference; response 1: oc; response 2: ic): predict ocxb, outcome(FP1) xb predict ocse, outcome(FP1) stdp predict icxb,...

Re: predict probability and CI

Hi George, Thank you for your kind reply. I have calculated the probabilities for each response of the multinominal model by hand. But I need 95% CI of prediction, and hence have to calculate standard error of prediction by hand as well (I am not sure the stata command predict se, stdp can work in t...

predict probability and CI

Hi, I find runmlwin is not compatible with command "margins". So, I fit a multinominal model and then calculate probabilities by hand using the expression like: "Pr(y = 1) = " exp([FP1]cons_1)/ /// (1 + exp([FP1]cons_1) + exp([FP2]cons_2) + exp([FP3]cons_3))" But I am not sure the correct way to cal...

p value in mcmc model

Hi, I fit multilevel nominal models using mcmc by running runmlwin in Stata. In their results tables, I found a pattern that the p values of coefficients tend to be smaller than expected. For example, there is one coefficient like this: Mean S.D. EES P 95% cred. Interval -.2965969 .1812569 548 0.049...

Dear George,

Thank you very much for your help. I will look through these iterations as you suggested.

Best wishes,

Re: stata imputed data in mlwin

Hi Chris, Thank you very much for your reply. I can confirm that there is no such problem if I use melogit command in Stata. The problem of Stata is the low-efficient maximum likelihood estimation, which can take dozens of days to estimate random slopes. MCMC in MLwin would be faster than ML. I shou...

stata imputed data in mlwin

Hi folks, I met some problem when I used runmlwin with multiply imputed data (done by stata mi command). My command is like this, a very simple one: sort commid idind2 wave mi est, cmdok noi sav(mlw, replace): runmlwin phi cons, level3(commid: cons) level2(idind2: cons) level1(wave) discrete(distrib...
