diabDat

<p>This dataset was simulated by sampling cases from an existing type 1 diabetes study (the original data could not be disclosed). The study investigates the relationship between concentration levels (low and high) of the islet antigen 2 antibody (IA2A) and several covariates of potential interest in type 1 diabetes patients (age, gender, and the number of copies (0,1 or 2) of the HLA-DQ2, HLA-DQ8 and HLA-DQ6.2 haplotypes).</p>

datasets

Implements a Markov Chain Monte Carlo algorithm to approximate
exact conditional inference for logistic regression models. Exact
conditional inference is based on the distribution of the sufficient
statistics for the parameters of interest given the sufficient statistics
for the remaining nuisance parameters. Using model formula notation, users
specify a logistic model and model terms of interest for exact inference.
