The model does not predict the outcome. The model partially predicts the outcome. The model perfectly predicts the outcome. The coefficient of determination is often written as R2, which is pronounced as “r squared.”.

A rule of thumb for OLS regression is that it isn't too impacted by heteroscedasticity as long as the maximum variance is not greater than 4 times the minimum variance. For example, if the variance of the ...
