- 요약Sequential probability ratio testing (PRT), which usually is applied in situations requiring a decision between two simple hypotheses or a single decision point, is extended to include situations involving k decision points and [(k 1)-choose-2] sets of simultaneous, simple hypotheses, where k1. The multiple-decision point or multiple-category SPRT procedure can be used to classify examinees into k 1 categories using computer adaptive methods. Computer simulations utilizing a 200-item pool of previously calibrated test items show that the multiple-category SPRT method controls misclassification error rates adequately, provided that the number of decision points is not too large. Twelve figures are included. (Contains 7 references.) (Author)
