Hi everyone!
                      I want to predict  wages for women who do not work,
so I am using the Heckman two step procedure to calculate wages for
participants accounting for selection. To predict wages for non
participants accurately I want to use the standard error of the
prediction instead of using just the mean. Using "predict  var , stdp"
predicts the standard error of the prediction taking into account the
Mills ratio? Or is just calculating the standard error of the linear
regression without taking into account the selection?

Thank you very much.

Regards.
