EJB 套件提供基本统计、离散概率、标准概率分布、假设测试、相关性和线性回归的功能。 统计模块 统计模块纳入了集中（均值）和（离散）数值集分散的标准定量测量的评估程序。此模块包含加权平均值、几何平均值、四分位数间范围、均值和标准差、样本方差和变异系数。 离散概率模块 离散概率模块封装离散概率和离散概率分布的基础。此组件包括分布的加法、条件概率、累积分布函数、均值和方差、预期值、协方差和涉及随机变量的表达式简化。 相关性和回归模块 允许用户调查两个变量之间的关系。这些发现可用于从其他变量的给定值预测一个变量。我们介绍线性（斯皮尔曼的，t-test，z-变换）和排名（斯皮尔曼的，肯德尔的）相关性，线性回归和条件手段。 标准概率分布模块 本模块协助开发包含二元、泊松、法线、日志正态、帕雷托、统一、超测和指数概率分布的应用程序。概率密度函数、累积分布函数和反向、均值、方差、偏斜度和峰度在适当和/或每个分布近似值时实现。我们还提供从给定分布随机生成数字的方法。 曲线拟合模块 曲线拟合模块提供一些过程，通过这些过程，可以按照给定数据集的最少正方形方法拟合线性函数和非线性函数，这些数据集可能显示测量误差，也可能不显示测量误差。我们还包括执行 ANNOVA 类型分析的功能，包括拟合度优度度量值，如 R-平方度量和 T-Test 统计。 置信区间和假设测试模块 在此组件中，我们介绍两个方面的推断统计称为置信区间和假设检验。

WebCab Probability and Statistics Developer License PLEASE READ THIS AGREEMENT CAREFULLY BEFORE USING THE COMPONENT. WEBCAB WILL ONLY GRANT A LICENSE FOR THIS COMPONENT IF YOU FIRST ACCEPT THE TERMS OF THIS AGREEMENT. In this license the vendor, WebCab Limited is referred to as WebCab. This J2EE Application is licensed on a per developer basis. A developer may use a license on several machines as long as they are not used concurrently nor used by another developer. This is the license agreement for one developer of the Probability and Statistics J2EE Application, herein referred to as the "Component". WebCab grants you a nonexclusive license for the J2EE Application. If WebCab grants you multiple licenses for the component, the terms of this Agreement apply to each license. In particular, a 4 developer team license is equivalent to four single developer licenses. The term "Component" means the Java(TM) Software with all of its features and capabilities as described in the product description. This component consists of machine-readable instructions, audio/visual content (such as images, text, recordings, or pictures), and related licensed materials. The Component is owned by WebCab, and is copyrighted and licensed, not sold. Use of the Full Version 1) Only one developer may use a license at any one time, except as otherwise stated in this section. You agree to ensure that anyone who uses the component (accessed either locally or remotely) does so only for your authorized use and complies with the terms of this Agreement. 2) You may merge the Component into another program. You must reproduce the copyright notice and any other marks of ownership on each copy, or partial copy, of the Program. You may modify the Program so as to solve problems related to the use of the component or to allow the program to work together with other products. 3) You may make a copy of the component for backup purposes. Charges for the Component 4) WebCab requires payment for the component based upon the number of developers who will use this component. The number of times the component is called by clients is not limited by the license agreement. This component is run-time royalty free. Payment must be made to the party (either WebCab or its reseller) from whom you acquired the component. 5) All maintenance updates (including service packs) will be distributed free of additional license cost. The License is fully transferable 6) You may transfer all your rights and obligations under a license for a Program to another party. 7) To transfer such rights and obligations, you must transfer a copy of this Agreement, the License Information, all other documentation (including proof of entitlement), and at least one complete, unaltered copy of the Program to the other party. Your license is then terminated. 8) A Program which WebCab licenses in multiples of two or more may be transferred in packs of one, two or more user licenses. Limitations on copying or disassembling licensed software 9) User may not take any steps, such as altering, decompiling, disassembling, reverse assembling, or reverse compiling, to derive the source code equivalent of the Licensed Program. Limitations on purposes of use; prohibition of commercial use of licensed materials 10) Under no circumstances may a Permitted User store any parts of the Component for the purposes of resale, redistribution. 11) The user may not sublicense, rent or lease the Component. 12) The Licensee may not use, copy, merge or transfer the Component except as provided for in this Agreement. 13) Any copyright notices or disclaimers included within the component or any accompanying screen displays may not be removed, obscured or modified in any way.
