After a couple of hours spent on the recent study on file sharing and CD sales (see March 30), I cannot make sense of it. I cannot tell what hypothesis was tested, and the methodology remains totally opaque.

Not being a statistician, such works are often beyond my ken, but usually I can figure out the basics -- theory, assumptions, hypothesis, approach. On this one, I can't. So I would like to invite, or perhaps challenge is a better word, those journalists, such as WaPo, and bloggers, such as Glenn Reynolds (March 30, item #5), who trumpeted the results to explain the study to me. I will be delighted to post any answers so people can laugh at my ignorance.
