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.
