The other day I stumbled accross an amazing PMML model API called jpmml. It's written in Java and supports PMML 4.1 (and older). Neural networks, random forests, regression and trees PMML models can be consumed and used for scoring.I decide...

Despite my preference for SAS over R, there are some add-ons to “basic” R that I’ve found that have made my learning process way easier. While I’m still in my infancy in learning R, I feel like once I found … Continue reading →Getting Started Using R, Part 1: RStudio is an article from randyzwitch.com,...

In short: R is a free intuitive programming language that is used by practitioners in a plethora of academic disciplines. Therefore, it is on the cutting edge, and expanding rapidly. It creates stunning visuals, works seamlessly together with LaTeX, has really good online documentation and the community is unparalleled. A week...

The recently announced Revolution Analytics / Zementis partnership goes a long way towards demonstrating how R fits into big-league production environments. A frequent complaint against R is that although R is fine prototyping tool it is not able to handle production environments. Well, that’s just not true. In fact, it is straightforward to build a model in R, translate...

There was a small earthquake in northern England on Tuesday. Barry Rowlingson felt the quake (it rattled the photographs on his wall), but didn't know how big of a quake it was because he didn't know how close he was to the epicentre. The British Geological Survey hadn't yet announced the quake, but did give access to seismograph readings,...

Whenever I'm asked, "Who uses R?", I usually rattle off a long list of job titles: statistician, analyst, quant, researcher ... and that's before all the domain-specific titles. It would be nice if there were a simple, succinct phrase to describe the process of working with, analyzing, and communicating with real data. At the new blog, "dataists", the inaugural...

According to Microsoft, the hottest three new tech majors are: Data Mining/Machine Learning/AI/Natural Language Processing Business Intelligence/Competitive Intelligence Analytics/Statistics – specifically Web Analytics, A/B Testing and statistical analysis Tim O'Reilly concurs. Of course, R features prominently in most of these areas -- follow the links I added above for examples -- and is growing rapidly, so learning R makes...

Tom Taverner introduced me to Benford’s Law as we were eating lunch together at a statistical computing conference: If you look at the first digits of data in many naturally-occuring datasets, a startling 30 percent of them are ones. “Pah!” I said. “That belies intuition! Why would one digit occur any more than another? I’d
