I am working with probit model with selection (heckman correction) for correcting estimates of heart failure prevalence from a sample survey. The problem is that the predicted probabilities p margin, p11, p10, p01 p00 and pcon , estimated with the comands of heckprobit postestimation returns missing values for those not participating in the study. Just psel has actual values for the entire sample. I tried to figure out why and how to correct the two models, without success. Could I have some help? Thanks
