Thank you to Win-Vector LLC General Partner Nina Zumel for stepping up her workload, allowing me take some time off from Win-Vector LLC (and time off from from revising chapter 8 of Practical Data Science with R 2nd Edition) to make time to help administer the Vietnam Rotary Global Grant mentioned below. This project is going to help over 1,600 farmers in Vietnam.

Heidi Kühn is a remarkable individual, and Roots of Peace and Rotary are remarkable organizations. It is an honor to work with all of you.

As with all projects- it feels like my part (the paperwork and supervision) is back under control. So back to research, clients, and the book (until something more is needed).

Binning Data in a Database

Roz King just wrote an interesting article on binning data (a common data analytics step) in a database. They compare a case-based approach (where the bin divisions are stuffed into code) with a join based approach. They share code and timings.

Best of all: rquery gets some attention and turns out to be the dominant solution at all scales measured.

Here is an example timing (lower times better):

So please check the article out.
