Abstract

Powerful software for statistical analysis is expensive. Here I present BrightStat, a statistical software running on the Internet which is free of charge. BrightStat's goals, its main capabilities and functionalities are outlined. Three different sample runs, a Friedman test, a chi-square test, and a step-wise multiple regression are presented. The results obtained by BrightStat are compared with results computed by SPSS, one of the global leader in providing statistical software, and VassarStats, a collection of scripts for data analysis running on the Internet. Elementary statistics is an inherent part of academic education and BrightStat is an alternative to commercial products.

摘要

功能强大的统计分析软件价格昂贵。在此，我介绍一款名为BrightStat的统计软件，它运行在互联网上且免费。本文概述了BrightStat的目标、主要功能和特性。文中展示了三个不同的示例运行，包括弗里德曼检验、卡方检验和逐步多元回归。将BrightStat得到的结果与SPSS（全球领先的统计软件提供商之一）以及VassarStats（一组运行在互联网上的数据分析脚本）计算得到的结果进行了比较。基础统计学是学术教育的一个固有组成部分，而BrightStat是商业产品的一个替代选择。
