Stepwise Regression and Stepwise Discriminant Analysis Need Not Apply Here: A Guidelines Editorial.

Thompson, Bruce

Educational and Psychological Measurement, v55 n4 p525-34 Aug 1995

Three problems with stepwise research methods are explored. Computer packages may use incorrect degrees of freedom in stepwise computations. In addition, stepwise methods do not identify correctly the best variable set of a given size. A third problem is that stepwise methods tend to capitalize on sampling error. (SLD)
