Hello,



I am running ivprobit regressions, and I have 4 endogenous continuous
variables -  I can run the regressions with only one endogenous
variable at a time,

but the ivprobit does not converge when I introduce all of them in
the regression.

It keeps on running and displays the following:



Fitting full model



Iteration 0:   log pseudolikelihood = -19244.386

Iteration 1:   log pseudolikelihood = -19243.321  (not concave)

...

Iteration 35:  log pseudolikelihood = -19242.958  (not concave)

Iteration 36:  log pseudolikelihood = -19242.958  (not concave)



Do you have any suggestions what to do in  cases like this?



Thank you,

Mariana
