Dear List members,
I have 150 sample household with different level of poverty. I have grouped this poverty level into three classes (1, 2, 3). I run multinomial probit regression model with this three categories of poverty as dependent variable and sociodemographic factors as independent variable. I use STATA 9.2 to run this program but it gave me the following error:
                  
<istmt>:  3499  _mprobit_weights_roots_laguerre() not found

My multinomial probit model specification is as follows:
mprobit eplbvarb hdage hdeducyrs age18 hhsize totul valuelskip

But, when I run the multinomial logit model with same variable specification then it works. 
I would very much appreciate if anyone can help me to figure out what is my mistake in running the multinomial probit model. 
Thank you in advance for your help.
Cheers,
Humnath
