Math is like music, statistics is like literature

An excellent link from Dr. Gelman's blog. Statistician Dick De Veaux says:

We haven’t evolved to be statisticians. Our students who think statistics is an unnatural subject are right. This isn’t how humans think naturally. But it is how humans think rationally. And it is how scientists think. This is the way we must think if we are to make progress in understanding how the world works and, for that matter, how we ourselves work.

GCSR

I will publish sample code (Python), and solutions for selected questions found in Andrew Gelman's excellent book Bayesian Data Analysis 2nd Edition (GCSR). Each posting will be solution for one question, if required, will include mathematical formulas (using mathurl.com), and Python, R code. R code will be copy and paste from Gelman's own solutions PDF. We might also include code from Guilherme Rocha (another Bayesian Statistics lecturer), or from Jeff Hart (Texas A&M), or from Brian Junker (Carnegie Mellon University).

To install R on ubuntu, apt-get install r-base and r-base-dev.

You can run the R code from command line using "R -f [file]". If there are plots displayed in the R code, they will be dumped into a file called Rplots.pdf in your current directory.

My Correction for Particle Filter Cookbook

The Python code correction I sent to SciPy.org - sponsored by Enthought - for particle filter has been made available by Alexander Borghgraef. The main page for the code is here.
