Hello useRs,

MBESS (Methods for the Behavioral, Educational, and Social Sciences) has recently been released and should be on all of the mirrors by now
(with binaries for Mac and Windows:


The major contribution of MBESS is confidence intervals for noncentrality parameters (t, F, and chi-square) and standardized effect sizes (e.g., the standardized mean and mean difference, R^2 for random or fixed effects, the coefficient of variation, the root mean square error of approximation, standardized regression coefficients) as well as sample size planning from the accuracy in parameter estimation (AIPE) approach, where the width of the observed confidence intervals is of interest (in addition to or instead of the power analytic approach to sample size planning).

This is the 10th release of MBESS and it is version number is now 1.0.0.

Detailed information about MBESS is available in the current issue of Behavior Research Methods
(http://www.psychonomic.org/BRMIC/contents.htm) as well as Journal of
Statistical Software (http://www.jstatsoft.org/v20/i08).
