I have a bunch of health metrics that needs to be regressed on each other in a probit model:


Code:
probit srhlt highbp diabetes cancer lungev heartp strokev psychev arth obese
All my variables are observed over 10 years. When I try to run the above command I get the following message:

Code:
outcome does not vary; remember:
                                  0 = negative outcome,
        all other nonmissing values = positive outcome
In my data I have "." as missing values. Here is an example of my data so that you can see it:

Array


Thanks in advance
