EJB 套件提供基本統計、離散概率、標準概率分佈、假設測試、相關性和線性回歸的功能。 統計模組 統計模組納入了集中（均值）和（離散）數值集分散的標準定量測量的評估程式。此模組包含加權平均值、幾何平均值、四分位數間範圍、均值和標準差、樣本方差和變數。 離散概率模組 離散概率模組封裝離散概率和離散概率分佈的基礎。此元件包括分佈的加法、條件概率、累積分佈函數、均值和方差、預期值、協方差和涉及隨機變數的表達式簡化。 相關性和回歸模組 允許用戶調查兩個變數之間的關係。這些發現可用於從其他變數的給定值預測一個變數。我們介紹線性（斯皮爾曼的，t-test，z-變換）和排名（斯皮爾曼的，肯德爾的）相關性，線性回歸和條件手段。 標準概率分佈模組 本模組協助開發包含二元、泊松、法線、日誌正態、帕雷托、統一、超測和指數概率分佈的應用程式。概率密度函數、累積分佈函數和反向、均值、方差、偏斜度和峰度在適當和/或每個分佈近似值時實現。我們還提供從給定分佈隨機生成數位的方法。 曲線擬合模組 曲線擬合模組提供一些過程，通過這些過程，可以按照給定數據集的最少正方形方法擬合線性函數和非線性函數，這些數據集可能顯示測量誤差，也可能不顯示測量誤差。我們還包括執行 ANNOVA 類型分析的功能，包括擬合度優度度量值，如 R-平方度量和 T-Test 統計。 置信區間和假設測試模組 在此元件中，我們介紹兩個方面的推斷統計稱為置信區間和假設檢驗。

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.
