After another (dry and fast) run around the Downs; Leo Held started the talks with one of my favourite topics, namely the theory of g-priors in generalized linear models. He did bring a new perspective on

I have to admit, first, that finding Waldo has been a difficult task. And I did not succeed. Neither could I correctly spot his shirt (because actually, it was what I was looking for). You know, that red-and-white striped shirt. I guess it sho...

(This algorithm, which modifies the target in a sort of reweighted partioned sampling to achieve faster convergence, has always been perplexing to me.)  They show that some

solaR 0.24 at CRAN

The version 0.24 of solaR is at CRAN and R-Forge. Some days before the 0.23 version was uploaded, but I had to make a quick fix to readMAPA: the url of http://www.mapa.es/siar has been changed to http://www.marm.es/siar. Moreover, this function has been renamed to readSIAR, although it is still available as readMAPA. Consequently the mode
