Mathematically convenient models for a search can be based on a prior representation of the hidden objects and their values by a mixture of Poisson processes. In simple cases, we can find the corresponding Bayes procedures to maximise expected net ga

Auditing is based on random sampling from the records of a company. This paper considers a Bayesian model for determining the sample sizes by finding a balance between the cost of sampling and the risk of leaving major faults undiscovered. It leads t

In this paper we assume that an oil company has k areas in which to drill and occurrences of undiscovered oilfields are represented by the model of Beale. The company is seeking a strategy for drilling that maximizes its expected return under the con

There have been many papers on biased coin designs and their use in balancing the numbers of patients allocated to different treatments in a clinical trial, without increasing the risk of selection bias. Less attention has been given to the correspon

The numerical solutions of two related variations of a sequential version of a form of the bioequivalence problem was presented in a report by Hwang (1991). It that report he referred to our unpublished results bounding the solutions and providing as

Lerche (1986) investigated a sequential testing problem concerned with deciding the sign of a normal mean. He demonstrated that a parabolic boundary which corresponds to

It is well known how to combine the significance levels observed in a number of independent experiments. When this number is a random variable determined by a stopping rule, the observed significance level can still be calculated if there is an accep

This paper is concerned with the problem of selecting the transition intensities for a Markov chain in continuous time so as to minimise the long-term average cost. Sufficient conditions are established for an optimal stationary policy using unbounde
