Hierarchical Bayesian Modeling in R
Hi Friends,
I'm trying to model the consumer decisions (Click-Through Rate and
Conversion) in Search Engine Advertising using a hierarchical Bayesian
binary logit. The input data is the weekly CTRs and Avg. Position for each
search keyword.
CTR is modeled as (for each keyword i and week j):
Pij = exp(C + Bi x Positionij + A1 x Lengthi + A2 x Brandi + A3 x
ProductSpecifici) / [1 + exp(C +

Metropolis acceptance rates
Is there a way to recover Metropolis-step acceptance rates AFTER
completing posterior draws?
The immediate application is in the probit.bayes and logit.bayes
models used by Zelig... which I believe is merely calling MCMCpack.
So one strategy, to which I am fixing to resort, is to call, say,
MCMClogit with verbose set to mcmc (or mcmc divided by an integer)
and then look at my screen.
