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.

Features:

• 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.

Licence:

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