Since 1996 the Bank of England inflation forecast has been published as a probability distribution and presented in what is now known as ‘the fan chart’. This post provides an overview on this useful visualisation tool and its Python implementation.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.Read more
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.Read more
Two simple ways to simulate a pair of independent standard normal distributions with Python code.
