NCSS/PASS/GESS 統計分析軟體

NCSS  - Statistical Analysis and Graphics

NCSS是容易學習的統計分析和圖形系統。
Features:
NCSS includes over 227 statistical procedures and plots. NCSS imports and exports all major spreadsheet, database, and statistical file formats. NCSS easily produces sharp, flexible graphics. NCSS output is easily transferred to popular word processors and presentation software such as PowerPoint.

PASS  - POWER ANALYSIS AND SAMPLE SIZE
市場上的最好的能力分析軟體

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.

GESS  - 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.

GESS comes with electronic (pdf) manuals that contain tutorials, examples, annotated output, references, formulas, and complete instructions on each procedure. And, if you cannot find an answer in the manual, our free technical support staff (which includes three Ph.D. statisticians) is available.
