Courses on data science

I took a <a href="https://www.coursera.org/course/compdata">course </a>in R through coursera and thoroughly enjoyed the class. I have been fiddling with R ever since and it is fun. I am excited to start the <a href="https://www.coursera.org/course/dataanalysis">course on data analysis </a>that starts on Jan 22. If you are interested in data science, then hop on

Classification of data

Data variables are also classified as

Whats the plan ?

I have been reading quite a bit about the "big data" , "data science" , "data scientist" etc topics and it sounds really fun and interesting. With my earlier interests in machine learning and data mining, all these terms resonate well with me. Just to strengten my basics, I got the "Statistics Hack" book by Bruce Fray. So I thought of starting a blog to document and share what I learn hoping that it'll be useful for someone as a reference. I am planning to write on topics / stat hacks that amuse me. Also will be posting any interesting development in the world of big data. If you are interested in anything related to big data or just want to simply refresh your knowledge in stats, plz feel free to jump in.
