Question

To test whether or not the population regression function is linear rather than a polynomial of order r,

A. look at the pattern of the coefficients: if they change from positive to negative to positive, etc., then the polynomial regression should be used.

B. check whether the regression R2 for the polynomial regression is higher than that of the linear regression.

C. compare the TSS from both regressions.

D. use the test of (minus1) restrictions using the F Minus Statistic.

Answer:To test whether or not the population regression function is linear rather than a polynomial of order r,

use the test of (minus1) restrictions using the F Minus Statistic.Therefore, option D is the correct answer choice.

Step-by-step explanation:The test of (r-1) restrictions using the F statistic is the most effective way to test whether or not the population regression function is linear rather than a polynomial of order r.

Therefore, ‘use the test of (minus1) restrictions using the F Minus Statistic’, option D is the correct answer choice.
