"Official"­ March 2014 Meetup

Predictive Analytics World is hosting our March Meetup
Agenda: 5:30 - 7:00 - PAW Reception
7:00 - 7:15 - Greeting from Eric Siegel

Note: You must RSVP to attend this meeting. Members who are on the meeting list are invited to attend the PAW reception which will be held in the Exhibit Hall

Max Kuhn
Max is Director of Nonclinical Statistics at Pfizer and author of R's caret package. He will talk about his work to refactor the caret package focusing on his method of classifying the predictive models included in caret and visualizing their relationships.

Antonio Piccolboni
Antonio is a data scientist, researcher and the major force behind RHadoop. He writes:

The `rmr` package made it possible to write Hadoop mapreduce programs in R and some users estimated the productivity gain to be roughly 30X! But that wasn't enough and we were asked if it was possible to make it easier. Thus `plyrmr` was conceived. It's the latest addition to the RHadoop open source project, supported by Revolution Analytics. It takes inspiration from the highly popular data manipulation package `plyr` and SQL to create a kind of specialized language within R that should look familiar to most R users, yet it is backed by the power of Hadoop. To get a feel for it, this is a snippet written with `plyrmr`:

input("/data/mtcars") %|%
group(carb) %|%
select(model = list(lm(mpg~cyl+disp))) %|%


Can you guess what it does? This talk will  explain how to write many more programs like this.

Megan Price
As the director of research at the Human Rights Data Analysis Group, Megan Price designs strategies and methods for statistical analysis of human rights data for projects in a variety of locations including Guatemala, Colombia, and Syria.

    I don't willingly share my slides because slides are not an appropriate replacement for technical writing (see but here is a write up that should convey the same information, without the introduction part ( I hope this gets you going and please don't hesitate with questions. The best way to submit them is the RHadoop user group:!forum/rhadoop.

      Great, thanks! May I ask is there any testing enviroment for RHadoop? There are a lot of things to set up the enviroment.

      Just ssh into it and go, I am afraid not. It'd be nice to have a pre-installed EC2 AMI, but we don't have it. There's one on the cloud market, but it seems scantly documented and I can't recommend it at this time. If anybody contributed a RHadoop ami it would be a great help to the project.

    I see that Meetup is back up! :-) But there is no room at the inn. :-( This appears to be a closed society, but perhaps it's not.

    I have been doing some data analysis in R and I am trying how to fit my data (on excel ) to a 3 parameter Weibull distribution.

      Hi Sadia, take a look at help(dweibull) at the R prompt.
