SAS vs. R.

Last month, I conducted a quick “flash survey” of my network and asked: Which do you prefer to use, R or SAS? I posted the initial results on my blog a few weeks ago, and as promised during the webinar for our Data Scientist Salary Study, we’ve finished up our deeper dive analysis of the data from over 1,000 respondents.[read more]

SAS vs. R.

Despite hearing more about R from clients and candidates than ever before, determining whether R was actually more popular than SAS proved difficult. A quick Google search for “R vs. SAS” returns more than a few pages dedicated to each side, as well as several heated LinkedIn discussions relating to the topic, with no definitive answers.[read more]

NoSQL Vs. RDBMS.

Comparing NoSQL and relational databases is lot like comparing the left and right sides of the brain. Too much focus on structural differences and attributes can overshadow the fact that we’re stuck with both sides of the brain and we need both to make the best use of sensory data.[read more]

I am working on a paper, for publication in early 2014, on the role of standards such as R, Hadoop and PMML in the mainstreaming of predictive analytics. As I do so I will be publishing a few blog posts. I thought I would start with a quick introduction to the topic now and then finish the series in the new year.[read more]

Choosing Your First Programming Language

November 25, 2013 by Bryan Halfpap

What language will you learn?

Every job requires the right kind of tool, and each programming language can be thought of as a separate tool. Just like some tools are good for hammering nails, driving screws, and leveling screws, some programming languages are innately more suitable than others for tasks like designing a website, interpreting text, or reacting to user input.[read more]

Big Data is Not Just Hadoop

November 11, 2013 by Steve Sarsfield

If you have a big data problem that needs to be solved, don’t jump right on the Hadoop bandwagon. Consider the impact that big data will have on your solutions and on your teams and take a long look at the new generation of columnar data storage and SQL-centric analytical platforms to get the job done.[read more]

Fantasy Football Modeling with R

October 17, 2013 by David Smith

My model pulls aggregated expert rankings from fantasypros, and I pass that data into a machine learning clustering algorithm called a gaussian mixture model to find tiers of players each week. Then I plot them in two dimensional space and the result is charts that let you easily decide your line up each week.[read more]

Alpha Testing RevoScaleR Running in Hadoop

September 16, 2013 by David Smith

At Revolution Analytics our mission is to establish R as the driver for Enterprise level computational frameworks. In part, this means that a data scientist ought to be able to develop an R based application in one context, e.g. her local PC, and then get it moving by changing horses on the fly (so to speak) and have it run on a platform with more horsepower with minimum acrobatics.[read more]

R User Groups Update

September 9, 2013 by David Smith

User groups are a great strength of the R community. Nothing beats face-to-face encounters with people from other companies and industries who are doing things with R that you haven’t thought about. It is one thing to come across a new application or some useful code on the web, but it is a much richer experience to have someone show you.[read more]
