Software to Simplify Statistical Practice ...

VisualStat Features

VisualStat is a comprehensive and versatile desktop statistics package that is simple for beginners, yet powerful enough for experts. It is designed for business, science, marketing, and education, with fully functional spreadsheet.

VisualStat is a major integrated development environment for R, allowing users to run R scripts and commands directly inside VisualStat. R output can be retrieved as native VisualStat output, and managed via highly flexible VisualStat containers. All VisualStat DataBook are manipulated as the R DataFrame, without any import/export procedure. Provides a platform-independent basic-statistics GUI (graphical user interface) for R, based on the many package.

VisualStat has a well-designed user interface with all its statistical and charting procedures easily selected from ribbon. Basic and frequently used commands can be shown continuously for instant access. With VisualStat DataBook, you can develop feature-rich database with an object-oriented, extensible set of classes to incorporate spreadsheet functionality into your set of data. VisualStat supports ODBC database connections.

As always with VisualStat, your reports are produced visually, and all details are commented. And you’ll be able to easily communicate them with others. All test results have an associated report which provides a short conclusion and other descriptions to assist in the interpretation.
