Charosel: A Computer Program Which Selects Qualitative Predictors for Qualitative Criterion Prediction Problems.
Moonan, William J.
Described is the theory and computer program of a new statistical procedure to find a parsimonious subset of predictor variables which have high predictive efficiency for a given criterion variable, and explained is application of the procedure to problems such as the identification of gifted kindergarten children. The procedure is seen to be most appropriate for Type D prediction problems, for which the criterion variable is represented by a set of categories and the predictor variables are represented by a set of qualitative variables. It is explained that the technique is based on a formula for calculating a posteriori probabilities and a simple decision function, and that models are evaluated by computing decision tables and an associative objective function for each predictor variable available. The program is thought to be applicable to prediction problems of the military, education, and medicine. Described is application of the procedure to the selection of questionnaire items most predictive of giftedness in kindergarten children. (DB)
