This document follows on from this page which uses R to analyse an Acute lymphocytic leukemia (ALL) microarray dataset, producing a heatmap (with dendrograms) of genes differentially expressed between two types of leukemia. On this page I deal with how to do this using Python and RPy.

2009/2010 OMOP Cup: Methods Competition

We are providing a large dataset that resembles observational data that can be extracted from insurance claims or electronic medical records. Your method will identify relationships in the data between drugs and medical outcomes (adverse events). The goal is to develop methods that correctly identify true drug-event associations while minimizing false positive findings. Methods will be evaluated by how closely they predict the known relationships that exist in the data.

Programmers Need To Learn Statistics Or I Will Kill Them All

I have a major pet peeve that I need to confess. I go insane when I hear programmers talking about statistics like they know shit when it’s clearly obvious they do not. I’ve been studying it for years and years and still don’t think I know anything. This article is my call for all programmers to finally learn enough about statistics to at least know they don’t know shit. I have no idea why, but their confidence in their lacking knowledge is only surpassed by their lack of confidence in their personal appearance.

The R programming language for programmers coming from other programming languages

I have written software professionally in perhaps a dozen programming languages, and the hardest language for me to learn has been R. The language is actually fairly simple, but it is unconventional. These notes are intended to make the language easier to learn for someone used to more commonly used languages such as C++, Java, Perl, etc.

Mechanical Turk: The Demographics ~~ (A Computer Scientist in a Business School)

One of the common misbeliefs about Mechanical Turk is that it is a virtual sweatshop, essentially taking advantage of poor people in third world countries that are doing tedious tasks for pennies. Therefore, many people are afraid of outsourcing research tasks on Mechanical Turk, being afraid that the results will be either of very poor quality, or they will not be representative of the actual U.S. population.

Voodoo Correlations: Have the Results of Some Brain Scanning Experiments Been Overstated?: Scientific American

VUL: We use that term as a humorous way to describe mysteriously high correlations produced by complicated statistical methods (which usually were never clearly described in the scientific papers we examined)—and which turn out unfortunately to yield some very misleading results. The specific issue we focus on, which is responsible for a great many mysterious correlations, is something we call “non-independent” testing and measurement of correlations. Basically, this involves inadvertently cherry-picking data and it results in inflated estimates of correlations.

WSJ.com

Your parents might have worried when you chose Philosophy or International Relations as a major. But a year-long survey of 1.2 million people with only a bachelor's degree by PayScale Inc. shows that graduates in these subjects earned 103.5% and 97.8% more, respectively, about 10 years post-commencement. Majors that didn't show as much salary growth include Nursing and Information Technology.

Presidential Election 2008 FAQ

This is an FAQ (Frequently Asked Questions list) for the 2008 United States Presidential Election. I need to disclose up front that I am an Obama supporter. However, with the exception of the very last question, this FAQ is designed as a collection of factual information (such as the latest poll results) and of analysis that is as objective as possible.
