The Twin Cities R User Group has been around for a little while, but has just launched a new site at meetup.com. Their next meeting will be on February 16, where Erik Iverson will be giving a talk on using R to generate dynamic statistical reports using R's literate programming tool, Sweave. If you're in the Minneapolis-St.Paul area, this...

Post-estimation results manipulation: Stata vs. R
Stata's new "margins" command is as powerful as "Zelig" package for R for the purpose of conducting post-estimation manipulation of the results (e.g. producing predicted probabilities, confidence intervals, etc.). While "margins" uses delta method, "Ze...

A new sponsorship program for local R user groups
Over the past year, Revolution Analytics has sponsored a number of local R user groups, and we've been thrilled to see the enthusiasm with which R users are coming together. This year, we decided to expand and formalize our sponsorship program, so that any local R user group, whether just starting up or already established, can benefit from additional...
Null Confusion
Talking a bit with my friend Jarrod about math stats and econometrics, we both came to the conclusion that the standard presentation for basic inference is lacking. In an intro or intermediate applied statistics course you learn about first and … Continue reading →
sab-R-metrics: Intermediate Scatter Plots
First off, I'll say it's been a whirlwind of a past few days. Thanks to David Smith at the Revolutions Blog for his kind words about the sab-R-metrics series and link back this way. Add in Ed Kupfer's posts at the APBRmetrics board, Harry Pavlidis at THT, Dave Allen at Fangraphs...

CPU and GPU trends over time
GPUs seem to be all the rage these days. At the last Bayesian Valencia meeting, Chris Holmes gave a nice talk on how GPUs could be leveraged for statistical computing. Recently Christian Robert arXived a paper with parallel computing firmly in mind. In two weeks time I’m giving an internal seminar on using GPUs for 
Zero Inflated Models and Generalized Linear Mixed Models with R.
