Presentation

The program CENSAD estimates parameters of linear mixed effects models for longitudinal gaussian left-censored data. Formal presentation of the model is published in: <see references below>.

The file on how to use CENSAD is censad4.txt.

The following files are downloadable:

• censad4.f source file in FORTRAN 77
• censad4.inf example of input file
• test.dat example of data file, from:
  http://www.blackwellpublishers.co.uk/rss/Volumes/Cv49p4.htm
• censad4u.out example of results using test.dat
• censad4.txt documentation

The program was written in FORTRAN 77. The file censad4.f has to be compiled or executable files are downloadable:

• Version for Unix station :  censad4u.out compiled for x86 station
• Version for DOS/Windows : censad4w.exe compiled for DOS/Windows
