I’ve posted quite a few code snippets over time, mainly in SPSS. This page is a brief overview for me to find my stuff. If you are looking for something and a link does not work, let me know. Also I have a few in here that do not have blog posts! So extras if you will.

This page is a current work in progress. Will continuing updating slowly over time.
