Controlling the Type I Error Rate in Stepwise Regression Analysis.

Download full text

Pohlmann, John T. – 1979

Three procedures used to control Type I error rate in stepwise regression analysis are forward selection, backward elimination, and true stepwise. In the forward selection method, a model of the dependent variable is formed by choosing the single best predictor; then the second predictor which makes the strongest contribution to the prediction of…
