We present two simple and efficient tests for the positive definiteness of a given function on the circle. The first criterion is an analogue of P61ya's theorem, and the second is a necessary condition in terms of derivatives. Some hints at applications in geostatistics are given as well. (~

A data augmentation algorithm is presented for estimating the hazard function and pointwise variability intervals based on interval censored data. The algorithm extends that proposed by Tanner and Wong for grouped right censored data to interval censored data. It applies multiple imputation and loca
