st: problem with xtprobit - number of quadrature points must be less than or equal to number of obs

["Vartia, Niini" <Niini.Vartia@iue.it>]

Dear Statalisters,
 
I am estimating random effects probit and I get the following message after trying to run the regression: number of quadrature points must be less than or equal to number of obs. Would anyone know to which promlem this is referring?
 
Thank you in advance.
 
Best regards,
 
Laura Vartia
