Last week, I began talking about using the base graphics in R. Those graphics were pretty bland, and my hope for the next two posts is to introduce some interesting additions to the basic graphics that come from R: color, legends, lines, shapes, multiple graphs side-by-side, text, point types, and custom axes. If you have missed...

Today I decided to begin more with visualizations and less with basic statistical analysis for sabermetrics using R. I'm not really here to teach the ins and outs of regressions and statistical tests, so once I get there, I'm hoping that those who have read this already have a decent understanding of those subjects before implementing them. ...

In the paper on the heat wave in Paris (mentioned here) I discussed changes in the distribution of temperature (and autocorrelation of the time series). During the workshop on Statistical Methods for Meteorology and Climate Change today (here) I o...
quanttrader.info is a good quantitative repository, where I found an idea about seasonal spreads play. The idea of seasonal pair trading differs from pairs trading in a way, that it doesn’t try to find deviation from the spread’s mean, but it looks at seasonal spread patterns. In some cases it is easier to find an
Several R functions take model formulae as parameters. Model formulae are symbolic expressions. They define a relationship between variables rather than an arithmetic expression to be evaluated immediately. Model formulae are defined with the tilde ope...

Just developed a small crawler to check my online content at binfalse.de in terms of W3C validity and the availability of external links. Here is the code and some statistics...
Summary: If you can get past the strange underlying story, then this gives a good introduction to R to someone with no programming experience. However, if you have any experience with other programming languages then another book is likely to be more suitable. Reference: Quick, J. M., Statistical Analysis in R: Beginners Guide, Packt Publishing,
Zero Inflated Models and Generalized Linear Mixed Models with R.
