WebCab Discrete Probability Enterprise JavaBeans component 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.

New Features: Self-Deploy, EAR Files

By clicking the self-install package the EJB component will be automatically deployed onto a supported local EJB application server. We also include multiple EAR les designed for each of the most widely used application servers (see details).

Product Details

The functionality implemented within this component are as follows:

Discrete Probability

• Discrete probability - a priori and relative frequency definition
• The Addition Law - used when combining event set or testing for their independence
• Conditional probability - the probability of an event assume that another event takes place
• Complementary event probability - the probability of a set of events not taking place

Discrete Probability Distributions

• Cumulative distribution function - the sum of the probabilities of a sequence of events
• Mean - the sum of the product of the probability of an event with its value
• Variance - a measure of the distributions spread from the mean
• Expected values - the expected value of the random variable
• Covariance - the covariance of two random variables
• Ro - the population correlation cofficient of two random variables

Expression with random variables and basic probability laws

• Simplify expresion - simplify expressions involving the mean, variance, expected values and covariance of random variables
• Union and Intersection - the basic formulae for calculating the union and the intersection of two or many events

This package also contains the following features:

• EAR Files - we provide individual customized EAR files for the most widely used application servers including IBMWebSphere 4.0/5.0Beta, BEAWebLogic 6.1/7.0, Oracle 9iAS, Ironflare Orion 1.5.2/1.5.4, Borland AppServer 5.0, Sybase EAServer and JBoss 2.4.4/3.0.0Beta
• Self-Deploy - the relevant servers EAR file will be self-deployed onto supported local application servers during the installation of the self-install package. The supported application servers include IBM WebSphere 4.0/5.0Beta, BEA WebLogic 6.1/7.0, Oracle 9iAS, Borland AppServer 5.0, Ironflare Orion 1.5.2/1.5.4 and JBoss 2.4.4/3.0.0Beta
• Synthetic JDBC - we use a JSP component to perform EJB calculations on SQL database columns from a remote DBMS. We apply an EJB function to certain rows from the database and list the output in HTML format. This is a powerful feature since it allows you to perform calculations in a JDBC manner without having to hardcode the EJB-to-JDBC transaction yourself as it is all done by the JSP within the Application Server
• Rational Rose Models - to assist designers of large enterprise applications we include Rational Models of the home and remote interface
