I have two regression Models: the first model with one dependent variable (Logarithm of income), one independent variable (Percentage of a proxy), and four control variables with datatype (nominal, percentage, Logarithm, percentage) the second model the same as the first model, but with different independent variable.
I need to know the required tests for each multi-regression model, and which test to combine the two models in one model.
thank you very much for any suggestion
