Model Selection with Small Samples

Recently, a new model selection criterion called the subspace information criterion (SIC) was proposed. SIC gives an unbiased estimate of the generalization error with finite samples. In this paper, we theoretically and experimentally evaluate the effectiveness of SIC in comparison with existing model selection techniques. Theoretical evaluation includes the comparison of the generalization mea...

Using Propensity Scores with Small Samples

Propensity scores are increasingly being used in large sample studies to control for pregroup differences. Because these scores are often used to match cases, they can result in sample attrition. In smaller sample studies, such attrition leaves too few cases for meaningful analysis. Alternatives when working with small samples are to use propensity scores as covariates to control for pre-group ...

The Analysis of Very Small Samples of Repeated Measurements

The statistical analysis of repeated measures or longitudinal data always requires the accommodation of the covariance structure of the repeated measurements at some stage in the analysis. The general linear mixed model is often used for such analyses, and allows for the specification of both a mean model and a covariance structure. Often the covariance structure itself is not of direct interes...

Microproteomics: analysis of protein diversity in small samples.

Proteomics, the large-scale study of protein expression in organisms, offers the potential to evaluate global changes in protein expression and their post-translational modifications that take place in response to normal or pathological stimuli. One challenge has been the requirement for substantial amounts of tissue in order to perform comprehensive proteomic characterization. In heterogeneous...

Learning From Small Samples: An Analysis of Simple Decision Heuristics

Simple decision heuristics are models of human and animal behavior that use few pieces of information—perhaps only a single piece of information—and integrate the pieces in simple ways, for example, by considering them sequentially, one at a time, or by giving them equal weight. It is unknown how quickly these heuristics can be learned from experience. We show, analytically and empirically, tha...
