## Installing R/RStudio on Ubuntu 14.04

September 22, 2014
By

My last experience with Linux was back in 2002/2003. At that time pretty much everything on Linux was done in the console. I remmember struggling for days with a simple Wifi connection because drivers were not readily available. Things have changed dramatically since then. Last week I installed Linux (Ubuntu 14.04)  on an old Windows laptop. […]

## new kids on the block

This summer, for the first time, I took three Dauphine undergraduate students into research projects thinking they had had enough R training (with me!) and several stats classes to undertake such projects. In all cases, the concept was pre-defined and “all they had to do” was running a massive flow of simulations in R (or […]

My forecasting textbook with George Athanasopoulos is already available online (for free), and in print via Amazon (for under \$40). Now we have made it available as a downloadable e-book via Google Books (for \$15.55). The Google Books version is identical to the print version on Amazon (apart from a few typos that have been fixed). To use […]

## Generate Random Inverse Gaussian in R

September 20, 2014
By

Needed to generate draws from an inverse Gaussian today, so I wrote the following Rcpp code: It seems to be faster than existing implementations such as rig from mgcv and rinvgauss from statmod packages. rename rrinvgauss as desired. The post Generate Random Inverse Gaussian in R appeared first on Lindons Log.

I presented today an arxived paper of my postdoc at the big success Young Bayesian Conference in Vienna. The big picture of the talk is simple: there are situations in Bayesian nonparametrics where you don’t know how to sample from the posterior distribution, but you can only compute posterior expectations (so-called marginal methods). So e.g. you cannot provide […]

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...

## What does CNN have in common with Carmen Reinhart, Kenneth Rogoff, and Richard Tol: They all made foolish, embarrassing errors that would never have happened had they been using R Markdown

September 19, 2014

Rachel Cunliffe shares this delight: Had the CNN team used an integrated statistical analysis and display system such as R Markdown, nobody would’ve needed to type in the numbers by hand, and the above embarrassment never would’ve occurred. And CNN should be embarrassed about this: it’s much worse than a simple typo, as it indicates […] The post What does CNN have in common with Carmen Reinhart, Kenneth Rogoff, and…

## Fun with .Rprofile and customizing R startup

September 18, 2014
By

Over the years, I've meticulously compiled–and version controlled–massive and extensive configuration files for virtually all of my most used utilities, most notably vim, tmux, and zsh. In fact, one of the only configurable utilities for which I had no special configuration schema was R. This is extremely surprising, given that I use R everyday. One »more
