Distributore Esclusivo

Simstat goes beyond mere statistical analysis. It offers output management features not found in any other program, as well as its own scripting language to automate statistical analysis and to write small applications, interactive tutorials with multimedia capabilities, as well as computer assisted interviewing systems.

 

Simstat supports not only numerical and categorical data, dates and short alpha-numeric variables but also memos and documents variables allowing one to store in the same project file responses to open-ended questions, interview transcripts, full reports, etc. Since all Provalis Research tools share the same file format, one can easily perform statistical analysis on numerical and categorical data using Simstat, perform qualitative coding on stored documents using QDA Miner or apply the powerful content analysis and text mining features of WordStat on those same documents. Moreover, the coexistence of numerical, categorical and textual data in the same data file gives a unique ability to explore relationships between numerical and textual variables or to compare qualitative codings or content categories between subgroups of individuals.

The Notebook window displays the statistical output for all analysis performed during a session. The notebook metaphor provides an efficient way to browse and manage outputs.

 

 

The text output of each analysis is displayed on a separate page.

Each page can be annotated or edited.

Empty pages can be inserted to put down ideas or remarks, sketch an analysis plan, or write down interpretation of results.

Tabs can be added to create sections in the notebook allowing storage of different kinds of analysis in different sections of the notebook.

An index of all analysis is automatically generated. This index can be used to quickly locate and go to a specific page, move pages within the notebook, or delete some pages.

Rich Text notebook allows one to change font attributes (bold, underline, strikeout, italic) and font colors.

Highlight tool allows to color passages of text.

Notebooks can be exported in Rich Text Format or in plain text.

 

CHART CREATION AND MANAGEMENT FEATURES

All high-resolution charts created during a session are displayed in the Chart window. This window can be used to view the charts and perform various operations on individual charts or on the entire collection of charts. For example, you can modify the various chart attributes, save those charts to disk, export them to another application using the clipboard or disk files, or print them. It is also possible to delete a specific chart or to modify the order of those charts in this window.
