We present two aspects of inferential statistics known as confidence intervals and hypothesis testing. Confidence intervals determine the level of confidence in pointwise statistics (e.g. mean, variance) of the sample in relation to the statistics for the entire population. With hypothesis testing the user can judge which of several hypotheses sampled evidence best supports.

Product Details
Within this J2EE Application we implement methods to calculate the following:

  • Normal Confidence Interval - used when large samples with greater than 30 elements are considered

    • Two-sided confidence interval for the mean, proportions, difference between means and difference between proportions
    • One-sided confidence interval for the mean, proportions and difference between means
    • Estimating the sample size for a given confidence of the mean
    • Estimating the sample size for a given confidence of the proportions

  • Student Confidence Interval - used when small samples with less than 30 elements are considered

    • Two-sided confidence interval for the mean and the difference between means
    • One-sided confidence interval for the mean

  • Normal Hypothesis Testing - used when large samples with greater than 30 elements are considered

    • Two-sided hypothesis testing for the mean, proportions, difference between means and difference between proportions
    • One-sided hypothesis testing for the mean, proportions, difference between means and difference between proportions

  • Student Hypothesis Testing - used when small samples with less than 30 elements are considered

    • Two-sided hypothesis testing for the mean, proportions and the difference between means
    • One-sided confidence interval for the mean, proportions and difference between means


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
