A Gibbs Sampling Approach to Logistic Regression

A (poor) Gibbs Sampling Approach to Logistic RegressionKyle BogdanGrant BrownDataSimulated based on known values of parameters (one covariate, dose).rats given different dosages of imaginary chemical, 4 dose groups with 25 rats in each group.Data generated three times under different parameters, three chains used for each data set. Gibbs Sampling For Logistic Data?Traditionally, binomial likelihood, prior on logit.Full Conditionals have no coherent form.Attractive, however, because it eliminates the need to reject iterationsAlgorithmGroenewald and Mokgatlhe, 2005Create Uniform Latent Variables Based on Y[i,j] = 0, 1Draws from joint posterior of Betas and U[i,j]pi[i] = p(uniform(01)
