| Abstract | C. Huberty (1994) recently noted that "It is quite common to find the use of 'stepwise analyses' reported in empirically based journal articles." Stepwise methods are used (incorrectly) by some researchers either to select variables to retain for further analyses or to evaluate the relative importance of various variables. Of course, stepwise methods have been shown not to be useful for either purpose (B. Thompson, 1995, 1999). Various authors have presented scathing indictments of many of these applications (C. Huberty, 1989; P. Snyder, 1991; B. Thompson, 1989). This paper explains the three major problems with stepwise applications in the context of discriminant function analysis. The paper considers both descriptive discriminate analysis and predictive discriminant analysis, noting that these are two very different applications (C. Huberty, 1994, and B. Thompson, 1995). It is suggested that stepwise methods not be used in multi-variate statistics. (Contains 20 references.)
