A general model for prediction and association is described for the situation in which both criterion and predictor(s) are discrete variables. The approach can be employed for the general case involving any number of predictors, and the related measures of multiple and partial association are described. (Author/GK)

A technique to estimate variances of weighted estimates in program evaluation is discussed. BRR estimates of variance are constructed from orthogonally weighted subsamples and can provide better estimates from complex samples than can other methods. Use of BRR is illustrated in a government evaluation of a food service program. (SLD)

A statistical model is presented for evaluating the effectiveness of the Demerit Points System of Victoria (Australia) in reducing traffic offenses. Estimates of the mean waiting time between offenses were made by maximum likelihood methods. Empirical results with 46,982 drivers--participants in a Driver Improvement Program--support the system's…
