Data is everywhere!

I was writing earlier today that I am getting really fed to using the same datasets over and over again.

I found time and read Gelman and Hill’s “Data Analysis Using Regression and Multilevel / Hierarchical Models“…Now, please do yourself a favour and get it (of course the paperback version ). Even for experienced or intermediate (myself) this will be a treat for your eyes and neurons. PS : (Confession) I didn’t like the Bayesian ...read more

Recently I was in need of testing a mean vector. I wrote a few lines of code in R and had it done perfectly. Hotelling test is one of the least interesting test to me. never really figured out why… At that time I had some time to search more about it. One of the
