Dear all,

After advising this forum hundreds of times for using STATA, I think its time to express my question.

I need to perform the tests of differences in means (and medians) between multinationals and domestic firms are based on univariate OLS (median) regressions. My problem is that I have one dummy called MNC that takes the value of 1 if the firm is an MNC and zero if domestic. How is possible to split that variable? Is this the right way of doing it? Thank you very much for your time and consideration.
