The Gaussian Processes Web Site

http://www.gaussianprocess.org/ is a very useful website that "aims to provide an overview of resources concerned with probabilistic modeling, inference and learning based on Gaussian processes. Although Gaussian processes have a long history in the field of statistics, they seem to have been employed extensively only in niche areas.

Parallel computations in R using the package "multicore"

The package "multicore" in R does parallel processing of R code on machines with multiple cores (or CPUs). The single threaded nature of R is painful specially in simulations when big loops are run. "multicore" package is a very useful package that enables R to be run on multi cores. This package, however, runs on Linux or Mac and not in windows.

Free E-Books From SpringerLink

As you might know, Springer Publishing has many of its book available online for free. Just recently, I was looking for some books in general Data Analysis topics and found several editorial books that seem to cover a wide range of topics in Data Analysis, I have provided the name and link of 5 of them that I found to be the top ones:

- Advances in Data Analysis and Classification, 2012 (link)

Regression Analysis with MATLAB: New Statistics Toolbox Capabilities in R2012A

On July 9th, Mathworks will present a webinar on capabilities of R2012a statistical toolbox. Though you may not have MATLAB's latest version installed on your system, there are still lots of common features in older versions which is somewhat the same as in R2012a. So, try not to miss this webinar.

Google Ngram Viewer: What we learned from 5 million books

"Ngram Viewer" is a tool (in Google Labs) that provides you interesting statistical knowledge of 5 million books (500 billion words) from across centuries. The following video shows how it works. There is a link to the "Ngram Viewer" page.

It might seem simple, but you could still enjoy the power of data analysis revealing some interesting facts (knowledge) about social and cultural phenomena in the history.

Permutation Tests in R!

“ There are many situations were parametric linear model significance tests are not optimal (including when data is notably non-normal, there are outliers, and when sample sizes are too small to trust asymptotic results). In these cases, permuation tests may be viable alternatives.” lmPerm package provides permutation tests for linear models in R. It can be used for ANOVA, ANCOVA, polynomial regression, and multiple regression.

Matrix Plot of Variables in MATLAB

Have you ever wondered how can you easily plot scatter plots of several variables and their own histograms together in MATLAB? This is something very useful when doing variance analysis on different parameters of a model.
