I've no idea.
Some time ago I had the idea of a blog about the kinds of statistics I use in my work. I didn't really think much about it until I noticed a couple of blogs by a friend of mine (Learning Statistics and Applying Regression by Jeremy Miles). Jeremy's blogs pointed me to the excellent Statistical Modeling, Causal Inference and Social Science by Andrew Gelman and Samantha Cook. As a consequence I'm not sure if this means that a psychological statistics blog is where all the cool academics hang out (though ... on reflection it seems unlikely) or whether I'm just slow to catch on (as usual).
The reason the blog is appearing now is really just to make a home for all sorts of odds and ends I've written or (half-written) that have never seen the light or day, or were published but have since become homeless. What this blog is about might never become clear, but then (as a newcomer to blogging) I suspect if I did have a clear idea what I was doing I'd write a book instead.
