摘要:

In a certain class of two—parameter exponential distributions, we consider minimum risk point estimation problems for one of the parameters. We propose to implement the sequential procedure of Bose and Boukai (1993) in smaller “pieces” along the lines of Mukhopadhyay and Sen (1993). Unlike the fully sequential procedure, one can obtain an unbiased estimator for the variance of the storpping number in a piecewise methodology. On top of this, the asymptotic second—order expansions of the regret functions for both the piecewise and fully sequential estimators are same up too(1) term and the piecewise sampling scheme is operationally more covenient. The effect on cost due to parallel processing is also discussed

摘要:

Application of the bootstrap to problems in sequential analysis is discussed. It is shown that the bootstrap can be used at any point during a sequential analysis to predict the final values of important quantities. This may lead to modification of the experiment with a view to obtain improved final performance with regard to the accuracy or other aspects of the experiment required

摘要:

Sightings of any member of a population of unknown sizeNoccur according to a homogeneous Poisson process. The processes are independent and have a common rate. Individuals are given a distinctive tag at the time they are first sighted. Various stopping rules have appeared in different areas of the literature for deciding when all the individuals in the population have been seen. The average time to termination of these rules is compared. Computational results suggest that the best performances are provided by two of the rules based on the cumulative waiting time to sight a given number of unmarked individuals

摘要:

This paper evaluates the average run length properties of some control procedures for monitoring the mean and the variance of a process. In particular, a comparison is made between theand Extreme—Value charts when the underlying distribution of the control chart statistic is not normal but is a mixture of normal distributions. It is shown that the Extreme—Value chart is the most efficient of the three charts when it is desired to detect the presence of mixture alternatives. Furthermore, the power of the Extreme—Value chart is close to the power of the likelihood ratio test corresponding to the underlying test problem

摘要:

A stopping rule is proposed for the purpose of bounding the mean integrated squared error of nonparametric regression estimates on an interval. The rale is designed to achieve sufficiently good fit in estimating the regression function, It is shown that the stopping rale is asymptotically efficient both in terms of sample size and fit, where the limit is taken as one requires increasingly better fit
