StatSoft, Inc. recently introduced STATISTICA Power Analysis, a comprehensive, extremely precise, and user-friendly research tool for analyzing all aspects of statistical power and sample size calculation.
Choosing the appropriate sample size is crucial to successful research and makes a powerful yet easy to use analysis tool a necessity in any reputable university, industry, or government research setting. STATISTICA Power Analysis uncovers the ideal sample size appropriate for the objectives of the research in question, assuring that valuable time and resources are not wasted.
The latest addition to the StatSoft line of high performance statistical software, STATISTICA Power Analysis, was developed with the same attention to detail as StatSoft's major product line, STATISTICA (which has received the highest rating in every comparative review in which it has been featured since its first release in 1993).
In addition to its overall quality and friendly user interface, STATISTICA Power Analysis offers unique quantitative features that set it apart from the competition. These features include the number of statistical procedures supported by the program, the speed of calculations, and the numerical precision of calculations (as measured by the number of significant digits produced by the program and its ability to correctly handle "extreme" numerical conclusions).
As with STATISTICA, using STATISTICA Power Analysis allows the user to produce and customize presentation-quality graphs quickly, intuitively and with minimal effort. And most importantly, it offers a wide variety of computational routines with unparalleled accuracy and power.
STATISTICA Power Analysis goes beyond the standard tests of "zero effect" offered in other power analysis programs and implements the most modern methods using interval estimation technology. Boasting a unique feature among programs of its type, STATISTICA Power Analysis calculates confidence intervals for a number of informative and important statistical quantities such as standardized effect size, the correlation coefficient, the squared multiple correlation, the sample proportion, and the difference between proportions. In addition, besides the wide range of distributions available in the probability calculator in all modules of STATISTICA, STATISTICA Power Analysis offers a number of specialized non-central distribution calculator functions that are useful in performing power calculations.
STATISTICA Power Analysis retails for $495 in the U.S. and similar pricing overseas. For more information about STATISTICA Power Analysis or STATISTICA visit the StatSoft web site at http://www.statsoft.com.au, e-mail info@statsoft.com.au, phone +61 3 9348 9422, or fax +61 3 9348 9420.
