Total VB Statistics - for Visual Basic 6.0 관련 정보

Add advanced statistical analysis to your Visual Basic applications.

Total VB Statistics allows VB developers to integrate advanced data analysis directly into any VB project, eliminating the need to import/export data to other programs or write complex statistical formulas. Functions include percentiles, t-Tests, frequency distributions, regressions, correlations, ANOVA, non-parametrics, probability and more. All results are placed in tables that you can query, sort, analyze, or add to forms and reports. Includes a royalty-free statistics DLL that you can distribute.

An interactive Scenario Designer simplifies creating and testing your analysis. Your scenario settings are saved for re-use, editing, or running. Examine the results and refine your analysis. No need for complex coding to specify what and how to analyze your data. It's all point and click. Once you're ready, it even generates the code you need to paste into your project. Adding statistical analysis to VB projects couldn't be easier!

Distributing your application is very easy. Just include our statistics ActiveX DLL file (under 1 MB) with your application and you're done. Royalty-free runtime distribution rights are included. Licensing on a per developer basis.

Two versions are included in the package, one for VB 5 and one for VB 6. The developer selects the version to install based on the application they are building. Both versions can be installed on the same machine.

There are two programs. An interactive Scenario Designer and an ActiveX DLL statistical analysis engine.

The Scenario Designer is an MDI application that allows the developer to interactively specify any Jet/Access database, the table, linked table, or query containing the data, the fields to analyze, the analysis type, and a variety of statistical options. Once the settings are specified, they are saved as a "scenario" which can be run, edited, or copied. The scenarios are stored in three system tables in the user's database. Only the settings, not the data to be analyzed or the analysis results are stored. Each scenario is assigned a unique Scenario ID that the programmatic interface references. The Scenario Designer includes a Code Generator feature that creates the code for running a scenario. A variety of coding options are included, and the developer simply copies and pastes it into his/her project.

The scenarios created in Total VB Statistics under VB 5 and 6 are identical and can be run by either version. They are also compatible with scenarios created in Total Access Statistics for Microsoft Access.

Programmatically, the developer needs to paste the code we provide and make sure a reference exists to the Statistics ActiveX DLL. When the analysis runs, progress events are fired for the developer to customize their own user interface. If the developer ignores these events, the processing occurs completely behind the scenes and are not visible to the user. For certain calculations, temporary tables may be needed. If so, they are created in a database in the Windows temp directory. This supports multi-user applications where multiple users may be performing analysis simultaneously.

In addition to running saved scenarios, there are two additional functions available. The first is to calculate the probability of a test value (Z value, student's t-test, Chi-Square, and F-Value). The second is the inverse (calculate a test value based on a probability).
