Question

Consider the following multiple regression model: y = β0 + β1x1 + …+ βkxk + u. Which of the following statements is correct?

Answer 1

Answer: Option D : All of the above.

Step-by-step explanation:

(1) The Cumulative Link Models assumptions can be summarized as, conditional on (x1, … xk)

(2) Whether normality of error u, and thus normality of y conditional on (x1, … xk) can be assumed, is an empirical matter

and (3) Normality of error u translates into normal sampling distributions of the OLS estimators are all correct statements describing linear regression.
