The Two Piece Normal Distribution
The two-piece normal, also called split normal, binormal, or double-Gaussian, results from joining at the mode the corresponding halves of two normal distributions with the same mode but different standard deviations.
Comparing Box-Muller and Marsaglia-Bray
In this post we compare the performance of our Python implementation for two popular methods to simulate samples from a pair of independent normal random variables: Box-Muller and Marsaglia-Bray.
Simulating Normal Random Variables
Two simple ways to simulate a pair of independent standard normal distributions with Python code.

JP Morgan Challenge
On July 4, 2019 I participated on the JP Morgan Corporate Challenge for the first time. A couple of days after the race the results were online and I could not help but taking a look at the data. Here are the highlights!

Anatomy of a Box Plot
This post is dedicate to one of the most popular graphs in data visualisation: the Box Plot, a simple tool which was introduced 40 years ago but remains in fashion.
