Optimal sampling strategies for two-stage studies.
The optimal allocation of available resources is the concern of every investigator in choosing a study design. The recent development of statistical methods for the analysis of two-stage data makes these study designs attractive for their economy and efficiency. However, little work has been done on deriving two-stage designs that are optimal under the kinds of constraints encountered in practi...
متن کاملTwo-stage sampling for etiologic studies. Sample size and power.
Preexisting computerized databases are potentially valuable sources of epidemiologic data. Since such databases are infrequently created specifically for etiologic research, data may be available for the exposure of interest and, through record linkage, for the endpoint of interest, but lacking for potential confounders. Because of the size of these databases, two-stage sampling is an efficient...
متن کاملNonparametric Independence Testing for Small Sample Sizes
This paper deals with the problem of nonparametric independence testing, a fundamental decisiontheoretic problem that asks if two arbitrary (possibly multivariate) random variables X,Y are independent or not, a question that comes up in many fields like causality and neuroscience. While quantities like correlation of X,Y only test for (univariate) linear independence, natural alternatives like ...
متن کاملTesting and interval estimation for two-sample survival comparisons with small sample sizes and unequal censoring.
While the commonly used log-rank test for survival times between 2 groups enjoys many desirable properties, sometimes the log-rank test and its related linear rank tests perform poorly when sample sizes are small. Similar concerns apply to interval estimates for treatment differences in this setting, though their properties are less well known. Standard permutation tests are one option, but the...
متن کاملAsymptotic Optimal Sample Sizes for Discovering a Promising Treatment in Phase II Group Sequential Clinical Trials
We propose an asymptotic optimal procedure for determining the per-study sample size of a series of Phase II clinical studies. The sequence of studies seeks to discover an active treatment among a sequence of treatments under evaluation. Each phase II study proceeds in r stages with r=1, 2, or 3. Our result serves two practical purposes. First, it yields asymptotic optimal sample sizes. Second,...
