About the Book

This unique software package was written to aid meta-analysts as they review the studies comprising research literatures. DSTAT 1.10 is proficient at computing study effect sizes -- including both d and r -- and at analyzing these values.

Working within Hedges' meta-analytic framework, DSTAT 1.10 features:

* Extensive and sophisticated routines for computing study effect sizes from a wide variety of source statistics. These routines, as well as the rest of DSTAT 1.10's routines, result in the presentation of both d- and r-values;

* An Effect-Size Manager that serves to organize effect sizes and coded study characteristics;

* Routines for computing composite means of effect sizes including an estimate of how consistent these values are;

* Outlier analysis to identify cases that result in inconsistencies and permit the user to remove them from analyses;

* Categorical model testing of effect sizes and study characteristics in the Effect-Size Manager. These models may include as many classes of effect sizes as have been defined by the user; and

* The ability to import information from external statistics programs in order to:

(a) create new data sets;

(b) fit categorical models to effect sizes (using Hedges & Olkin's TWD-, TWDS-, and TW-terms); and

(c) fit continuous and/or multivariate models to effect sizes.

DSTAT 1.10 is one of most refined programs for conducting meta-analysis available today. All options are menu-driven and the user can customize many operating specifications. The manual, in addition to documenting program features, provides a tutorial for first time meta-analysts.

In addition, DSTAT 1.10 offers the following:

* improved ability to derive effect sizes (g or equivalent);

* greater flexibility in managing DSTAT data sets;

* more flexibility and options in analyses; and

* enhanced reliability and functionality.
