If all of these vars are in your model and you are using listwise
deletion of missing data, then your maximum N is 6017. Ergo Stata's
5709 cases sounds much more in the ballpark than Limdep's 15,469. I
am not sure how Limdep handles missing data, but you'll need to
figure that out. If worse comes to worst, create an extract that only
has cases with no missing values and use it with Limdep.

Nick, here is the situation
I have data with total of 15469 observation now when I am running
probit or tobit is stata and limdep the number of observation in the
output table is coming to be quite different. The number of
observation in limdep is 15469 and in stata it is 5709. Below I am
providing the summary statistics of the variable used in regression.
