Total VB Statistics

Description

ActiveX DLL callable from VB with advanced stats analysis functionality.
Total VB Statistics offers a wide range of statistical functions for Visual Basic programmers using Microsoft Jet Engine databases. Any Access/Jet table or linked table such as SQL Server, dBase or Paradox table can be analysed. Multi-table Select Queries and an unlimited number of records can be analysed. Total VB Statistics eliminates the need to export data to other programs for statistical analysis. Perform a wide range of statistical functions with all results in Microsoft Access tables. View, sort, query or display the results and add it to reports. Total VB Statistics comprises two parts: an interactive Statistics Scenario Designer that is a standalone program for specifying the database, data, fields and analysis to perform and an ActiveX DLL component that performs the analysis. This latter is under 1 MB in size and is the only file that needs to be included with VB applications in order to add statistical analysis. Total VB Statistics is available on a per developer basis and includes unlimited, royalty free distribution rights for that developer. It supports VB 5.0 and 6.0. A five-developer package is also available.
