The Bayesian errors-in-variables + random effects Poisson regression model I built to estimate the relationship between prevalence and incidence for our team’s (i.e. MAP’s) *vivax* malaria mapping ambitions has appeared in Malaria Journal recently. That’s the second epidemiology paper I’m on as second author, so once I get my equivalent paper on the *falciparum* prevalence-incidence relationship published (fingers crossed) I can probably start calling myself an epidemiologist. While it wasn’t an overly complicated model to build or fit (w/ JAGS) I’d claim that it’s still more sophisticated than the norm for regressions in astronomical studies: for starters our likelihood function acknowledges the discrete sampling distribution of the response (as we encourage in this COIN paper) and ditto for the predictor. In this case we also use a hierarchical structure with a Dirichlet prior to borrow strength between the various phenotype relapse zones: that is, we allow each to have a unique intercept and slope if necessary, but where the observations are sparse we allow multiple zones to share a common intercept and slope if warranted by the data. If only I’d caught the typo in our description of the likelihood function in the paper where the rate is erroneously exponentiated twice (instead of just once).

Congratulations! That’s a nice looking plot. Is there any culture in epidemiology of putting papers on the arxiv, or similar freely accessible places?

Some colleagues have asked me about arXiv but no one really seems to use it in epi. Having said that, Malaria Journal is largely open access and you can even post online comments on the papers … a dangerous feature of the journal, perhaps!
