The twilight zone!

I had the weirdest impression this morning when, while looking at entries on defensive sampling on Google, I ended up on a webpage that suspiciously looked like my own work! After getting over the first shock (it was way too early for shouting out loud!), I went up the directory hierarchy to understand at last that my entry into the collective book Computational Statistics by James E. Gentle, Wolfgang Härdle, and Yuichi Mori has a free version available on the Web, as all entries of this book have…. This available web-book can be quite useful as additional material when teaching an introductory course on computational statistics.
