EJB Suite offers functionality from Basic Statistics, Discrete Probability, Standard Probability Distributions, Hypothesis Testing, Correlation and Linear Regression. Statistics Module The Statistics module incorporates evaluation procedures of standard quantitative measures of centrality (mean) and dispersion of (discrete) numerical sets. This module incorporates weighted averages, geometric mean, Inter-Quartile range, mean and standard deviation, sample variance and the coefficient of variation. Discrete Probability Module The Discrete Probability module encapsulates the foundations of discrete probability and discrete probability distributions. This component includes the addition law, conditional probability, cumulative distribution function, mean and variance of a distribution, expected values, covariance and simplification of expressions involving random variables. Correlation and Regression Module Allows the user to investigate relationships between two variables. These finding can be used to predict one variable from the given values of other variables. We cover linear (Spearman''s, t-test, z-transform) and rank (Spearman''s, Kendall''s) correlation, linear regression and conditional means. Standard Probability Distributions Module This module assists in the development of applications that incorporate the Binomial, Poisson, Normal, Lognormal, Pareto, Uniform, Hypergeometric and Exponential probability distributions. The probability density function, cumulative distribution function and inverse, mean, variance, Skewness and Kurtosis are implemented where appropriate and/or their approximations for each distribution. We also offer methods which randomly generate numbers from a given distribution. Curve Fitting Module The Curve Fitting module offers procedures by which linear and non-linear functions can be fitted in accordance with the least squares approach to a given data set which may or may not exhibit measurement errors. We also include functionality which performs ANNOVA type analysis including goodness-of-fit measures such as the R-Squared measure and T-Test statistic. Confidence Intervals and Hypothesis Testing Module Within this component we present two aspects of inferential statistics known as confidence intervals and hypothesis testing.

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 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.
