st: mlogit with alternative specific variables

["Peter Haan" <phaan@diw.de>]

Dear Statalist,
my question is about the multinomial logit model.
My model includes both, individual and alternative specific variabels. 
So far I have estimated my model with clogit, which works fine.
Now I want to translate the clogit model into a mlogit including the 
alternative specific variables. The reason for the model chnage is that 
eventually I want to estimate a discrete time hazard model, which can be 
written as a mlogit.
As far as I understand Maddala (1983) mlgoit and clogit should be 
equivalent with both individual and alternative specific variabels.
However, so far I did not get the equivalent probabilities when I am 
using mlogit, the problem I suppose is the wrong data structure.
My structure: persnr outcomevariable (1 or2 or3)     indspecific vars    
X(kat1)      X(kat2)      X(kat3)
Hence, each ind has one row

Do you have an idea in which form I need to construct my data?

thank you very much for you help
peter
