Adaptive optimal allocation in stratified sampling methods
In this paper, we propose a stratified sampling algorithm in which the random drawings made in the strata to compute the expectation of interest are also used to adaptively modify the proportion of further drawings in each stratum. These proportions converge to the optimal allocation in terms of variance reduction. And our stratified estimator is asymptotically normal with asymptotic variance e...
متن کاملInteger programming formulations applied to optimal allocation in stratified sampling
The problem of optimal allocation of samples in surveys using a stratified sampling plan was first discussed by Neyman in 1934. Since then, many researchers have studied the problem of the sample allocation in multivariate surveys and several methods have been proposed. Basically, these methods are divided into two classes: The first class comprises methods that seek an allocation which minimiz...
متن کاملOptimal Allocation for Stratified Telephone Survey Designs
1. THE CURRENT STATUS OF TELEPHONE SURVEY DESIGNS The two stage random digit dialing design for sampling telephone households, first proposed by Mitofsky (1970) and more fully developed by Waksberg (1978), has been widely employed in telephone surveys. The Mitofsky-Waksberg technique capitalizes on the fact that working residential numbers (hereafter referred to as WRNs) tend to be highly clust...
متن کاملAdaptive strategy for stratified Monte Carlo sampling
We consider the problem of stratified sampling for Monte Carlo integration of a random variable. We model this problem in a K-armed bandit, where the arms represent the K strata. The goal is to estimate the integral mean, that is a weighted average of the mean values of the arms. The learner is allowed to sample the variable n times, but it can decide on-line which stratum to sample next. We pr...
متن کاملA biobjective method for sample allocation in stratified sampling
The two main and contradicting criteria guiding sampling design are accuracy of estimators and sampling costs. In stratified random sampling, the sample size must be allocated to strata in order to optimize both objectives. In this note we address, following a biobjective methodology, this allocation problem. A two-phase method is proposed to describe the set of Pareto-optimal solutions of this...
