Big Data Starts with R

Traditional IT infrastructure is simply unable to meet

the demands of the new “Big Data Analytics” landscape. Many enterprises are turning to the “R” statistical programming language and Hadoop (both open source projects) as a potential solution. This webinar will introduce the statistical capabilities of R within the Hadoop ecosystem. We’ll cover:

An introduction to new packages developed by Revolution Analytics to facilitate interaction with the data stores HDFS and HBase so that they can be leveraged from the R environment
An overview of how to write Map Reduce jobs in R using Hadoop
Special considerations that need to be made when working with R and Hadoop.

We’ll also provide additional resources that are available to people interested in integrating R and Hadoop.

Upcoming Webinars

Wed, Dec 14th
11:00AM – 11:30AM PT

Revolution R Enterprise – 100% R and MoreR users already know why the R language is the lingua franca of statisticians today: because it’s the most powerful statistical language in the world. Revolution Analytics builds on the power of open source R, and adds performance, productivity and integration features to create Revolution R Enterprise. In this webinar, author and blogger David Smith will introduce the additional capabilities of Revolution R Enterprise.

Revolution Webinar: New Features in Revolution R Enterprise 5.0 (including RevoScaleR) to Support Scalable Data AnalysisRevolution R Enterprise 5.0 is Revolution Analytics’ scalable analytics platform. At its core is Revolution Analytics’ enhanced Distribution of R, the world’s most widely-used project for statistical computing. In this webinar, Dr. Ranney will discuss new features and show examples of the new functionality, which extend the platform’s usability, integration and scalability

Graphs in Statistical Analysis

One of the seminal papers establishing the importance of data visualization (as it is now called) was the 1973 paper by F J Anscombe in http://www.sjsu.edu/faculty/gerstman/StatPrimer/anscombe1973.pdf

It has probably the most elegant introduction to an advanced statistical analysis paper that I have ever seen-

1. Usefulness of graphs

Most textbooks on statistical methods, and most statistical computer programs, pay too little attention to graphs. Few of us escape being indoctrinated with these notions:

(1) numerical calculations are exact, but graphs are rough;

(2) for any particular kind of statistical data there is just one set of calculations constituting a correct statistical analysis;

(3) performing intricate calculations is virtuous, whereas actually looking at the data is cheating.

A computer should make both calculations and graphs. Both sorts of output should be studied; each will contribute to understanding.

Of course the dataset makes it very very interesting for people who dont like graphical analysis too much.

From http://en.wikipedia.org/wiki/Anscombe%27s_quartet

The x values are the same for the first three datasets.

Anscombe’s Quartet
I		II		III		IV
x	y	x	y	x	y	x	y
10.0	8.04	10.0	9.14	10.0	7.46	8.0	6.58
8.0	6.95	8.0	8.14	8.0	6.77	8.0	5.76
13.0	7.58	13.0	8.74	13.0	12.74	8.0	7.71
9.0	8.81	9.0	8.77	9.0	7.11	8.0	8.84
11.0	8.33	11.0	9.26	11.0	7.81	8.0	8.47
14.0	9.96	14.0	8.10	14.0	8.84	8.0	7.04
6.0	7.24	6.0	6.13	6.0	6.08	8.0	5.25
4.0	4.26	4.0	3.10	4.0	5.39	19.0	12.50
12.0	10.84	12.0	9.13	12.0	8.15	8.0	5.56
7.0	4.82	7.0	7.26	7.0	6.42	8.0	7.91
5.0	5.68	5.0	4.74	5.0	5.73	8.0	6.89

For all four datasets:

Property	Value
Mean of x in each case	9 exact
Variance of x in each case	11 exact
Mean of y in each case	7.50 (to 2 decimal places)
Variance of y in each case	4.122 or 4.127 (to 3 d.p.)
Correlation between x and y in each case	0.816 (to 3 d.p.)
Linear regression line in each case	y = 3.00 + 0.500x (to 2 d.p. and 3 d.p. resp.)

But see the graphical analysis –

While R has always been great in emphasizing graphical analysis, thanks in part due to work by H Wickham and others, SAS products and language has also modified its approach at http://www.sas.com/technologies/analytics/statistics/datadiscovery/

SAS Visual Data Discovery combines top-selling SAS products (Base SAS, SAS/STAT® and SAS/GRAPH®), along with two interfaces (SAS® Enterprise Guide® for guided tasks and batch analysis and JMP® software for discovery and exploratory analysis).

While ODS Statistical graphs is still not as smooth as say R’s GGPLOT2 http://tinyurl.com/ggplot2-book, it still is a progressive step

Pretty graphs make for better decisions too !

My Digital Trail

Someone I know recently mentioned that I have an extensive Digital Trail. I do.

I have 7863 connections at http://www.linkedin.com/in/ajayohri, 31 likes at https://www.facebook.com/ajayohri and 19 likes at https://www.facebook.com/pages/Ajay-Ohri/157086547679568, 409 friends (and 13 subscribers) at https://www.facebook.com/byebyebyer .On twitter I have 499 followers at http://twitter.com/0_h_r_1 and 344 followers at http://twitter.com/rforbusiness , and even on Google Plus some 617 people circling me at https://plus.google.com/116302364907696741272 (besides 6 other pages on G+)

Even my Youtube channel at http://www.youtube.com/decisionstats is more popular than I am in non-digital life. my non existant video blog at http://videosforkush.blogspot.com/ and my poetry blog at http://poemsforkush.wordpress.com/, and my comments on other social media, and my blurbs on my tumblr http://kushohri.tumblr.com/, and you get a lot of my psych profile.

Why do I do leave so much trail digitally?

For one reason- I was a bit of introvert always and technology set me free, the opportunity to think and yet be relaxed in anonymous chatter.

For the second reason- I am divorced and my wife got my 4 yr old son’s custody. Even though I talk to him once a day for a couple of minutes, somehow I hope when he grows, he reads my digital trail , maybe even these words, on the kind of man I was and the phases and seasons of life I went through.

That is all.

Software as a Religion ( SaaR)

The decline of organized religion and debate about such matters in the Western Hemisphere has been co-related to the increase in debates and arguments (again mostly) in the Western Hemisphere on software. Be it the PC vs Mac, the Microsofties vs Open Sourcers, the not so evil Google versus fans of Facebook, considerable activity is now being done by human beings in terms of social interaction on the merit’s and demerit’s of each software bundle. Perhaps for the first time in human history these interactions are being captured digitally on medium (that is hopefully longer lasting than papyrus).

Will this lead to newer branches of psychologists, sociologists (Goodwin’s law is too simplistic but an effort)

Even software as a religion is plausible, all they need is another college drop-put whizkid to find a way to make it effective.

Religion as a software has of course been around for several millennium.
