• Intuitive, Windows-standard graphical environment.
  Use the CaseEditor, EGRETâs powerful data editor, to create, modify and view data.
  Use descriptive menus and dialog boxes to define a regression model for analysis.
  The EGRET Results Workbook window presents analysis results and post-fit diagnostics.
  The Output Log Window accumulates in the background all output and generated results from the current session.
  EGRET's default control settings can be easily viewed or changed.
  Save current workspace with current settings for quick-restart.
• The nearly 300-page manual includes tutorials and descriptions of all windows and dialog boxes, the analysis models and post-fit regression diagnostics, descriptive statistics and the case-editor, and other features.
• Appendices list model fitting procedures and example data sets, and are followed by references and an index.
