 I have a dataset for children and parents and would need ro run a
probit model on child school attendance(binary dependent variable)
with the parents education, age, sex etc as independent variable. If I
have observations where there is only one parent in the household I
can't seem to run the probit properly. Here is an example

ID             Child school                Father's education (in
years)                     Mother's education (in years)

1                      1                                            5
2                     1                                            4
3                     1                                            2
4                     0                                            5
5                     1                                           -

In the above example, if I run a probit

probit child_school    father_edu    mother_edu

on the 5 observations where the first 3 households have both parents
and the 4th household only has the father and the 5th household only
has the mother, stata drops the 4th and 5th observation because of the
missing value. How do I get stata to consider running all the 5
observations for analysis of 2 parent household and single parent

Grateful for any suggestions. Thanks
