Abstract
The issues of treatment assignment is ordinarily dealt with within the framework of testing aptitude treatment interaction (ATI) hypothesis. ATI research mostly uses linear regression techniques, and an ATI exists when the aptitude treatment (AT) regression lines cross each other within the relevant interval of the aptitude variable. Consistent with this approach is the use of the points of interaction of AT regression lines as treatment-assignment rule. The replacement of such rules by monotone, nonrandomized (Bayes) rules is proposed. Both continuous and dichotomous criteria for treatment success are considered. An example of the latter is evaluated using a ma...
