WebFor male, the intercept is 1.73761. For female, the intercept is 1.73761 + 0.77765 = 2.51526. Note that since we set “male” to be the first level (also called the base level or reference level), the intercept corresponds to the intercept for “male”. We can change the base level by the relevel() command: Weblikelihood) to zero. In the multiple regression model, when we set the derivative to zero, we get the matrix equation xT (y x b) = 0 (27) But the term in parentheses is just e, so the equation is xT e = 0 (28) Expanding out the matrix multiplication, 2 6 6 6 4 P P i e i i x i1e..
