April 17, 2006. StatSoft, Inc. announces the general release of a new STATISTICA product, Variance Estimation and Precision (VEPAC), for the analysis of variance used widely for research and manufacturing applications.

VEPAC was developed by StatSoft in close collaboration with representative users, including scientists, engineers, and statisticians from one of the largest global Pharmaceutical Research and Manufacturing companies in the world.

The Variance Estimation and Precision (VEPAC) product provides a comprehensive set of techniques for analyzing data from experiments that include both fixed and random effects. With VEPAC, you can obtain estimates of variance components and use them to make precision statements while at the same time comparing fixed effects in the presence of multiple sources of variation. In the VEPAC module, an alternative to ANOVA estimation is provided by restricted maximum likelihood estimation (REML). The REML method is based on quadratic forms and requires iteration to find a solution for the variance components.
