Hi, I am having problems with running a probit regression and don't understand where the problem comes from since with the original data set I was able to get correct estimates. To that data set I have added extra variables and upon running the regression I get now multiple estimates of the same predictor: Deviance Residuals: Min 1Q Median 3Q Max -1.17741 -0.00001 0.00000 0.00001 1.17741 Coefficients: Estimate Std.
