Not sure if other and authors are used to this, but I hadn't anticipated the fact that packages would change or no longer be maintained and this would mean i would have to regularly update my book to reflect these changes. peopleanalytics-regression-book.org

THANK YOU to everyone who has bought my regression textbook, or used it in their college course or learning program, or donated in lieu. In 2023, more than $10k was donated to good causes. The textbook remains free at peopleanalytics-regression-book.org

Feel like giving these 1858 school math questions a try? Remember they didn't have computers or calculators back then so no cheating! link.medium.com/hcIBmWGvaAb

As a statistical technique, survival analysis kicks ass. And like most brilliant work it was born out of necessity. Here's my latest blog piece on this link.medium.com/69Tc5BnbJzb

I’ve been hearing a lot of non-coders suggest that will mean that people don’t need to learn to code in the future. I can’t tell you how ridiculous that sounds to me.

I had a lot of fun solving these theoreticallu and then validating my solutions through algorithmic estimations link.medium.com/28jdth1cgzb

A couple of nice questions for those who enjoy solving infinite series. I found a couple of different ways of solving these and will publish my approaches soon.
