Model description
Logistic regression is commonly used to relate a dichotomous response y to explanatory
variables. This example use simulated data to examplify logistic regression with random effects.
A full description of the model can be found here: logistic.pdf
Comparison with WinBUGS
WinBUGS is a software package for formulating and fitting
Bayesian hierarchical models. From a user perspective WinBUGS and ADMBRE appear similar because both
software packages:
 Allows models with random effects.
 Contain a full programming language, and hence give the user great flexibility in formulating statistical models.
 Are automatic, in the sense of hiding the technical details of computation from the user.
Despite these similarities, the underlying computational technology is very different.
In this example we compare WinBUGS and ADMBRE with respect to computation times on simulated data.
The R (SPlus) script used to generate data in the input
format for both WinBUGS and ADMBRE can be found here: logistic.s.
You can modify this script to generate new datasets.
