Within this component 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 decide which of several hypotheses sampled evidence best supports.

New 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.

Product Details

Within this component we implement methods to calculate the following:

Normal Confidence Interval - used when large samples with >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 < = 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 >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 <=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 package also contains the following features:

• JDBC Mediator - An server side EJB component which mediates between a EJB component, clients and DBMS. The mediator moves most of a clients JDBC calls to the server and hence greatly increases the speed of JDBC client applications.
• 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
• UML Models - to assist software architects we include UML diagrams
• 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
• 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
