This page contains notes on some common and a couple of specialized statistical topics. Notes on common topics like Elementary Probability and Statistics and Linear Models are developed based on the courses I have taught over the years at various Universities around the globe, while those on Bayesian Statistics, Markov Chain Monte Carlo and the WinBUGS Case Study were done under a sponsored industry project as a part of my research interest. Notes on the common topics are somewhat incomplete. Click on the topic below to download the pdf files containing these notes.
