The Correlation and Regression EJB component allows the user to investigate relationships between two or more variables and then use these findings to predict one variable from the given values of other variables. We cover linear (Pearman's, t-test, z-transform) and rank (Spearman's, Kendall's) correlation, linear regression and conditional means.

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 files designed for each of the most widely used application servers (see details).

Product Details

This component includes the following functionality:

• Statistic quantities
  • Mean - calculates the arithmetic mean
  • Sample variance - calculates the sample variance
• Correlation coefficients
  • Pearson's product moment correlation coefficient - the most widely used linear correlation coefficient for a data set
  • t-test, z-transform - provides an analytic framwork to establishing a confidence level for Pearson's coefficient
  • Spearman's and Kendall's rank correlation coefficients - measure the association between two variables of an ordered data set
• Regression line - using the method of least squares to determine the line of best fit
• Confidence interval for the conditional mean - determine the confidence interval for the true regression line

This package also contains the following features:

• GUI Bundle - we bundle a suite of graphical user interface JavaBean components (with a site-wide licence) allowing the developer to plug-in a wide range of GUI functionality (including charts/graphs) into their client applications
• JDBC Compliant - this Enterprise Application is fully JDBC compliant
• EAR Files - we provide individual customized EAR files for the most widely used application servers including IBM WebSphere 4.0/5.0, BEA WebLogic 6.1/7.0, Oracle 9iAS, Sun ONE AppServer 7, Ironflare Orion 1.5.2/1.6.4, Borland AppServer 5.0, Sybase EAServer 3.6 and JBoss 2.4.4/3.0.0
• 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 4.0/5.0, BEA WebLogic 6.1/7.0, Oracle 9iAS, Borland AppServer 5.0, Ironflare Orion 1.5.2/1.6.0 and JBoss 2.4.4/3.0.0
• UML Models - to assist software architects we include UML diagrams
