Suppressor Variable Effects: Toward Understanding an Elusive Data Dynamic.
Henard, David H.
The important and sometimes difficult-to-grasp concept of regression suppressor variable effects is explored. An inquiry into the phenomenon of suppressor effects is accomplished via a synthesis of the existing literature and the use of a small heuristic data set to improve the accessibility of the concept. Implications for researchers are also forwarded and it is suggested that the search for suppressor variables in an effort to remove unwanted predictor variable variance may prove less efficient than the search for additional predictor variables which directly explain variance in the criterion variable of interest. However, when they are present, suppressor effects can be critical to note and interpret. (Contains 1 figure, 3 tables, and 14 references.) (Author)
