If a regression model uses the L1 Regularization technique, then it is called Lasso Regression. If it used the L2 regularization technique, it’s called Ridge Regression. We will study more about these in the later sections. L1 regularization adds a penalty that is equal to the absolute value of the magnitude of the …

This is a di cult question. Theoretically, the Gamma should be the right choice when the dependent vari-able is real-valued on a range from 0 to 1: And the Gamma is suitable when you suspect the linkage be-tween mean and variance is\ xed".
