Statistical adjustments for brain size in volumetric neuroimaging studies: Some practical implications in methods

Statistical adjustments for brain size in volumetric neuroimaging studies: some practical implications in methods.

Volumetric magnetic resonance imaging (MRI) brain data provide a valuable tool for detecting structural differences associated with various neurological and psychiatric disorders. Analysis of such data, however, is not always straightforward, and complications can arise when trying to determine which brain structures are "smaller" or "larger" in light of the high degree of individual variabilit...

Adjustment for whole brain and cranial size in volumetric brain studies: a review of common adjustment factors and statistical methods.

In this article we address analytic challenges inherent in brain volumetrics (i.e., the study of volumes of brains and brain regions). It has sometimes been assumed in the literature that deviations in regional brain size in clinical samples are directly related to maldevelopment or pathogenesis. However, this assumption may be incorrect; such volume differences may, instead, be wholly or partl...

Methods for Census 2000 and Statistical Adjustments

This article outlines procedures for taking the US census, making adjustments, and evaluating the results. The census turns out to be remarkably accurate. Statistical adjustment is unlikely to improve on the census, because adjustment can easily put in more error than it takes out. Indeed, error rates in the adjustment are comparable to if not larger than errors in the census. The data suggest ...
