Sequential estimation of powers of a scale parameter from delayed observations
The problem of sequentially estimating powers of a scale parameter in a scale family and in a location-scale family is considered in the case when the observations become available at random times. Certain classes of sequential estimation procedures are derived under a scale invariant loss function and with the observation cost determined by a convex function of the stopping time and the number of observations up to that time.

Stability estimating in optimal sequential hypotheses testing
We study the stability of the classical optimal sequential probability ratio test based on independent identically distributed observations when testing two simple hypotheses about their common density : versus . As a functional to be minimized, it is used a weighted sum of the average (under ) sample number and the two types error probabilities. We prove that the problem is reduced to stopping time optimization for a ratio process generated by with the density . For being the corresponding...
