Beyond the Sum-Difference Plot

Bland–Altman plot
From Wikipedia, the free encyclopedia

Bland–Altman plot example
A Bland–Altman plot (Difference plot) in analytical chemistry and biostatistics is a method of data plotting used in analyzing the agreement between two different assays. It is identical to a Tukey mean-difference plot, the name by which it is known in other fields, but was popularised in medical statistics by J. Martin Bland and Douglas G. Altman.[1][2]

How did I end up reading a 30 year old book on density estimation?

Simple, I wanted to make violin plots for efficiency scores, and they shouldn’t have any density below zero. Here is a sneaky way to sneak such a figure out of Python/Seaborn: https://github.com/mwaskom/seaborn/issues/525#issuecomment-97651992

The truncation makes them look more like gyro meat than violins.
