The Analysis of Nonlinearity Via Linear Regression with Polynomial and Product Variables: An Examination

Sockloff, Alan L.

Review of Educational Research, 46, 2, 267-91, Spr 76

Three linear models (Fixed, Random, and Provisional) and their inferential counterparts are presented and discussed. The three linear models are considered in relation to the analysis of nonlinearity, and limitations in the use of polynominal and product variables are discussed. Several exemplary research papers are examined and reconsidered in view of the conclusions of this paper. (Author/DEP)
