Hello everyone,
I have the following vector (A) with 73 observations:


A | Freq. Percent Cum.
-----------+-----------------------------------
ob | 2 2.74 2.74
lb | 57 78.08 80.82
pb | 3 4.11 84.93
unb | 11 15.07 100.00
------------+-----------------------------------
Total | 73 100.00


I want to estimate the predicted probability for each of the four outcomes (ob, lb, pb, unb) by running an intercept-only bayesian multinomial logistic regression. I type "bayes: mlogit A" and I get the following error:

new vector must be 1 x 3
r(198);

Any idea why I get this? NB: standard "mlogit A" command works fine.

Any help is really appreciated! Thanks a lot
