Hi I am wondering why my probit model does not provide the coefficient for the first category for my categorical variable. For example, There are 3 regions I am interested in and the model only shows me the coefficients for regions 2 and 3. I am interested in seeing how my q142 (is binary yes/no) varies across the 3 regions. The same issue occurs for education.
Please let me know if perhaps I should be using a different model to find the associations between my covariates and q142. Thank you!
