Hello, do you know how to test the assumptions of linearity and homoscedasticity when you have a dichotomous independent variable ? Thanks so much in advance
I am getting this warning: "Warnings There are no valid cases for models with dependent variable O. Statistics cannot be computed. No valid cases found. Equation-building skipped." what do I do

Explanations in your video are great; but, I find it surprising that no one has mentioned the quality. All of your videos are difficult to see. Blury
