The Statistica Workbook (*.stw) is a flexible output management facility based on the powerful ActiveX technology. Technically speaking, workbooks are "ActiveX containers" that enable you to manage all Statistica documents (e.g., spreadsheets, graphs), as well as all other ActiveX compatible documents, such as Microsoft Excel worksheets or Microsoft Word documents.

Each workbook contains two panels: an Explorer-style navigation tree on the left and a document viewer on the right. The navigation tree (workbook tree) can be hierarchically split into various nodes allowing you to organize your files in logical groupings (e.g., all analysis outputs, all macros created for a project, etc.). Tabs at the bottom of the document viewer (workbook viewer) are used to easily navigate the children of the currently selected node.

Workbooks help to organize sets of output files (e.g., spreadsheets, graphs, reports, macros, non-Statistica files, etc.) that have been created or used (e.g., reviewed) during the analysis of a data file.
