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 (Spearman's, t-test, z-transform) and rank (Spearman's, Kendall's) correlation, linear regression and conditional means.

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 framework 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 - determines the confidence interval for the true regression line

We also include a client tool and a template FSA (UK) report:

  • Correlation Tool - we provide a correlation client tool with an easy and intuitive GUI for searching for pairs of data series (i.e. database columns) which satisfy a user defined correlation rule. The rule can to built using the implemented correlation related measures.
  • Reduce the Cost of Capital according to FSA (UK) regulations - We provide a template report and a step by step guide which shows how to establish that the cost of capital for a pair of highly correlated financial products traded within a regulation institution can be reduced. Our tool in this instance can search for all pairs of traded products for which the cost of capital can be reduced.

This product also contains the following features:

  • GUI Bundle - we bundle a suite of graphical user interface JavaBean components (with 1, 2, 4 or site-wide license) allowing the developer to plug-in a wide range of GUI functionality (including charts/graphs) into their client applications
  • 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 1.5.2/1.6.0, 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 system architects we provide UML diagrams of this component
