Sample Size and Sample Allocation

2015
Most survey statisticians recognize that determining an appropriate sample size is a crucial part of the design of a sampling strategy. In fact, it has a large impact on the overall cost and efficiency when producing reliable statistics on a phenomenon.

Allocation in Stratified Sampling as a Game

Journal of the American Statistical Association, 1972
Abstract We consider here the problem of allocating sampling effort among strata when there is no useful information on the within-stratum variability. We show that in a natural game theoretic analogue proportional allocation is a unique good strategy.

The sampling resource allocation problem

IEEE Transactions on Communications, 1991
A sampling resource allocation problem formulation for determining the optimal sample size for each of multiple sampling activities competing for a single sampling resource is described. The problem is formulated as a nonlinear knapsack problem with lower and upper binding restrictions.

Dynamic Allocation in Survey Sampling

American Journal of Mathematical and Management Sciences, 1991
SYNOPTIC ABSTRACTConsider the problem of estimating a linear combination of means from populations with different, unknown variances. We study the Bayes version of the problem and derive the dynamic programming optimality equations for the determination of optimal multi stage sequential sample size allocation procedures for several pertinent loss ...

Sampling in Time Allocation Research

Ethnology, 1993
Sampling behavior by direct observation is a common technique in field studies of behavior (Lehner 1979; Martin and Bateson 1986). There are two ways to sample behavior: (1) focus on individuals and monitor them continuously for a period of time; (2) record the behavior of individuals at random times throughout the period of research.

On sample size allocation in auditing*

Contemporary Accounting Research, 1988
Abstract. Scott (1973) suggested a model for sample size allocation in auditing which uses as a criterion the minimization of costs of misestimation and sampling costs. We extend his model by incorporating the binomial‐normal model for errors of Menzefricke and Smieliauskas (1984).Résumé.

Sample size allocation in multiregional equivalence studies

Pharmaceutical Statistics, 2018
With the increasing globalization of drug development, the multiregional clinical trial (MRCT) has gained extensive use. The data from MRCTs could be accepted by regulatory authorities across regions and countries as the primary sources of evidence to support global marketing drug approval simultaneously.

Sample allocation for statistical multiresolution compressed sensing

2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
We model the compressible signal with the two states Gaussian mixture distribution and consider the sample distortion function for the recently proposed Bayesian optimal AMP decoder. By leveraging the rigorous analysis of the AMP algorithm, we are able to derive the theoretical SD function and a sample allocation scheme for multi-resolution statistical

Optimal Budget Allocation for Sample Average Approximation

Operations Research, 2013
The sample average approximation approach to solving stochastic programs induces a sampling error, caused by replacing an expectation by a sample average, as well as an optimization error due to approximating the solution of the resulting sample average problem.
