As part of the work she's doing for her PhD, Christina has done some (fairly major, I'd say!) review of the literature about prevalence studies on PCOS $-$ that's a rather serious, albeit probably fair to say quite under-researched area. When... [Read more...]

As part of the work she's doing for her PhD, Christina has done some (fairly major, I'd say!) review of the literature about prevalence studies on PCOS $-$ that's a rather serious, albeit probably fair to say quite under-researched area. When it came to analysing the data she had collected, ...

Lately, we've been spending a lot of time "stress-testing" our method for the computation of the Expected Value of Partial Perfect Information (EVPPI $-$ I know: the terminology is a bit strange and possibly not-very helpful, as "perfect" information d... [Read more...]

A couple of weeks ago, we've uploaded the new version of BCEA on CRAN, to include the function implementing our method for the computation of the EVPPI based on INLA-SPDE $-$ I've also already mentioned this here.While this is a stable versio... [Read more...]

Disclaimer: I'm fully aware of the obvious conflict of interest here, but also I think that this looks really good, so I'll write about it anyway.This post is to highlight that Marta's and Michela's book on Spatial and Spatio-temporal Bayesian Mod... [Read more...]

My friend and colleague Andreas sent me a link to a working paper published by a statistician at the University of Christchurch (New Zealand) and discussed here. The main idea of the paper was to use a Bayesian model to predict the number of futur... [Read more...]

The last two days have been kind of a very interesting mini-tour for me $-$ yesterday the Symposium that we organised at UCL (the picture on the left is not a photo taken yesterday) and today the workshop on efficient methods for value of inf... [Read more...]

We're about to release the new version of BCEA, which will contain some major changes.A couple of changes in the basic code that should improve the computational speed. In general, BCEA doesn't really run into troubles because most of the computations ... [Read more...]

Chris, Richard and I tested this last March in Canada (see also here) and things seem to have gone quite well. So we have decided to replicate the experiment (so that we can get a bigger sample size!) and do the short course this coming November (... [Read more...]

Just after Easter, I'll go for a very quick trip to lovely Girona, where Marc Saez has invited me to give two talks.The first one will be a re-run of the short course on INLA that I did at Bayes Pharma last year. It's scheduled (and prepared) as a 3... [Read more...]

While preparing the practicals for our course at the University of Alberta, I've discovered something kind of interesting. I'm sure this is nothing new and actually people who normally use both OpenBUGS and JAGS have already figured this out.&nbsp... [Read more...]

Panagiotis Petrou has posted a link to a recent paper of his, which develops a cost-effectiveness analysis of a drug used as a second-line treatment of renal carcinoma. The analysis is based on a Bayesian Markov model. But (from an incredibly self... [Read more...]

The other day I was having a quick look to the newspapers and I stumbled on this article. Apparently, Pornhub (a website whose mission should be pretty clear) have analysed the data on their customers and found out that the town of Ware (Hertfords... [Read more...]

I was really impressed by the very smooth process through which my paper on cost-effectiveness analysis in the presence of structural zero costs (which I've already mentioned for example here and here; the related R package is described here) has ... [Read more...]

Very shortly, I'll upload the newest release of BCEA, my R package to post-process the output of a (Bayesian) health economic model and produce systematic summaries (such as graphs and tables) for a full economic evaluation and probabilistic sensitivit... [Read more...]

As I was responding to the points raised by two referees and the editor on my paper on cost-effectiveness with structural zeros (the preliminary version was here, while I have presenting it in a few talks and discussed it here, here, here and here... [Read more...]

Despite the map here, I'm not going to talk about yet another fraction of the former Soviet Empire which is taken the form of a people's republic, possibly with witty British Ambassadors.In fact, I'm going to talk about the Stan workshop that I have be... [Read more...]

Last summer I have applied for a NIHR Research Methods fellowship. Earlier this week the results have come out and they have liked my proposal, which is of course great news. The idea of this project is to critically evaluate the stepped... [Read more...]
