The Validity of Polynomial Regression in the Random Regression Model.
Cramer, Elliot M.; Appelbaum, Mark I.
Review of Educational Research, v48 n4 p511-15 Fall 1978
Assuming conditional normality and independence, standard estimation and hypothesis testing procedures for regression coefficients are the same whether using fixed x values, random x values or mixed fixed and random values. Contrary to Sockloff's suggestion, polynomial regression is useful with either fixed or random models. (See EJ 142 050). (CP)
