PASS 2008 - POWER ANALYSIS AND SAMPLE SIZE

市場上的最好的能力分析軟體,

PASS Beats the Competition!

PASS performs power analysis and calculates sample sizes. Use it before you begin a study to calculate an appropriate sample size (it meets the requirements of government agencies that demand technical justification of the sample size you have used). Use it after a study to determine if your sample size was large enough.

PASS lets you solve for power, sample size, effect size, and alpha level. It automatically displays charts and graphs along with numeric tables and text summaries in a portable format that is cut and paste compatible with all word processors so you can easily include the results in your proposal.

PASS is a standalone system. Although it is integrated with NCSS, you do not have to own NCSS to run it. You can use it with any statistical software you want.

GESS 2006 - Gene Expression Statistical System for Microarrays

GESS makes statistical analysis of microarray gene expression data fast and easy. With this well-documented package, you will not have to worry about complex programming or confusing statistical output. Because this software was developed by a company with over 20 years of experience creating commercial statistical software, you will be confident with your results.

GESS is a standalone system. Although it is integrated with NCSS, you do not have to own NCSS to run it. You can use it with any statistical software you want.

Array Quality and Filtering
Graphical and numeric summaries, designed to quickly alert the user to artifacts, bad spots, spatial anomalies, or poor arrays, are easily obtained for each array. Expression values may be filtered according to well-described criteria. Several normalization procedures are also on hand.

A wide variety of statistical analyses is available. Each technique is well-documented and described in easy-to-understand terms. Graphical summaries of statistical output help interpret the results. Follow-up statistical analyses are obtained with over 150 statistical procedures in NCSS.
