In Bayesian nonparametrics, many models address the problem of density regression, including covariate dependent processes. These were settled by the pioneering works by [current ISBA president] MacEachern (1999) who introduced the general class of dependent Dirichlet processes. The literature on dependent processes was developed in numerous models, such as nonparametric regression, time series data, meta-analysis, to cite butContinue reading “3D density plot in R with Plotly”

Daily casualties in Syria
Every new day brings its statistics of new deaths in Syria… Here is an attempt to learn about the Syrian uprising by the figures. Data vary among sources: the Syrian opposition provides the number of casualties by day (here on Dropbox), updated on 8 February 2012, with a total exceeding 8 000. We note firstContinue reading “Daily casualties in Syria”
Triathlon data with ggplot2
As Jérôme and I like so much to play with triathlon data, it is a pleasure to see that we are not alone. Christophe Ladroue, from the university of Bristol, wrote this post yesterday: An exercise in plyr and ggplot2 using triathlon results, followed by part II, way better than ours, here and here. For example,Continue reading “Triathlon data with ggplot2”
Artist view of crimes in London
At first sight, one could think this picture is a scale model of some narrow moutains, like Bryce Canyon… Actually it represents crimes in East London, an cardboard artwork by the Londoner artist Abigail Reynolds, called Mount Fear. Here is what can be read on the artist’s webpage: The terrain of Mount Fear is generatedContinue reading “Artist view of crimes in London”
Googling Bayes’ pictures
I am writing way too many posts in a row on Google tools. I promise I will think about something else soon. I find amusing the possibility to launch a search in Google images by just dragging a picture into the search box, instead of typing text. I remember that Pierre told me about itContinue reading “Googling Bayes’ pictures”
