LR-Mesh is a Delphi program for the visualization of habitat models.
The program draws the response surface of a logistic regression model against two explanatory variables as a mesh.


  • The response surface is calculated on the basis of a regression model that is pasted to a textbox
  • Variables and axis ranges may be customized.
  • Simple interaction terms may be included.
  • The model result is corrected for each variable that is not displayed in the diagram (option).
  • The pseudo-3D-diagram may be rotated around the z-axis and tilted.
  • A reference point may be moved over the response surface indicating the predicted probability (z-value).
  • The diagram may be saved as wmf-File.
  • The graph can be displayed as a mesh or as a coloured surface.

System requirements:

  • The program is compiled on a Windows NT-System. It may be run on Windows 98, NT or 2000 (R)
  • The decimal separator must be a point! - Check the system properties.


  • The program may be used by everyone without any licence fee.
