[Gretl-users] bivariate probit in a loop

Dear all, I'm currently estimating a bootstraped bivariate probit through a progressive loop and retrieve each time the $yhat matrix. At some point, the execution is interrupted with the "warning": The statistic you requested is not available Is there a perfect prediction symptom behind this message isn't it? Can one, in such a loop, skip cases where the MLE estimation is not technically possible? Best, Artur
