Data Analysis (with R) on Coursera

Posted to Statistics  |  Tags: , ,  |  Nathan Yau

Jeff Leek, an Assistant Professor of Biostatistics at the Johns Hopkins Bloomberg School of Public Health, is teaching a course on data analysis on Coursera, appropriately named Data Analysis.

This course is an applied statistics course focusing on data analysis. The course will begin with an overview of how to organize, perform, and write-up data analyses. Then we will cover some of the most popular and widely used statistical methods like linear regression, principal components analysis, cross-validation, and p-values. Instead of focusing on mathematical details, the lectures will be designed to help you apply these techniques to real data using the R statistical programming language, interpret the results, and diagnose potential problems in your analysis.

The course starts on January 22, 2013.
