Published in Towards Data Science·Sep 24, 2018A new plot theme for Matplotlib — GadflyIntroduction I’ve made a plotting theme for Matplotlib that’s inspired by the default plotting theme used in Gadfly for the Julia programming language. Typically I’d just write the code in Julia, which is what I’ve done for many of my previous blog posts. However, since upgrading to Julia v1.0, I’ve been…Python3 min readPython3 min read

Published in Towards Data Science·Sep 10, 2018Probability concepts explained: probability distributions (introduction part 3)In my first and second introductory posts I covered notation, fundamental laws of probability and axioms. These are the things that get mathematicians excited. However, probability theory is often useful in practice when we use probability distributions. Probability distributions are used in many fields but rarely do we explain what…Statistics14 min readStatistics14 min read
