Today I released a new version of my twopiece Python package in pip. It now supports the three families of two-piece distributions: Scale, Shape (new!)
and Double (new!). Read more
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.
A brief recollection of the history of the two-piece normal distribution discovery: 119 years from the first publication of Gustav Fechner original work until its latest re-discovery.
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.
Two simple ways to simulate a pair of independent standard normal distributions with Python code.
