I’m interested in studying the personal income of veterans and non veterans from 2006 to 2012. Additional variables include the period of the veteran’s service, whether the person is self or wage-employed, and demographic variables such as race and sex.
Everytime I submit for my extract, however, I receive a panel filled with mostly veterans or vice-versa. How can I get a data set that has an even balance (50%) of my two key binary variables; class of worker and veteran status? I’ve tried tweaking the sample sizes to no avail.
