Linear versus Nonlinear Analysis in the Measurement of Effects in a Quasi-Experimental Design.

Vooijs, Marcel W.; Van der Kamp, Leo J. T.

Evaluation Review, v15 n5 p625-38 Oct 1991

A two-step procedure is developed for the analysis of pretest-posttest data. Nonlinear canonical correlation analysis is followed by covariance analysis of optimally scaled pretest and posttest measures. The procedure is available in the computer program CANALS. Advantages of the two-step procedure are discussed. (SLD)
