The Logit-Normal: A ubiquitous but strange distribution!

September 30, 2021 by Will Kurt

In this post we explore the very curious logit-normal distribution, which appears frequently in statistics and yet has no analytical solutions to any of its moments. We end with a discussion of Nietzsche and what Dionysian statistics might mean. It’s a bit of an odd post that’s for sure.

Technically Wrong: When Bayesian and Frequentist methods differ

April 28, 2021 by Will Kurt

Exploring how Frequentist and Bayesian methods differ when looking at the common problem of predicting misfires in extra-dimensional alien technologies. We explore the nice property that Bayesian statistics are mathematically correct and then consider that sometimes being “technical wrong” does work out.

Inference and Prediction Part 2: Statistics

January 05, 2021 by Will Kurt

In part 2 of our series exploring the relationship between Inference and Prediction we explore modeling Click Through Rate as a Statistical modeling problem so that we can more deeply understand the role of Inference in modeling.

Inference and Prediction Part 1: Machine Learning

December 15, 2020 by Will Kurt

This post is the first in a three part series covering the difference between prediction and inference in modeling data. Through this process we will also explore the differences between Machine Learning and Statistics. We start here with statistics, ultimately working towards a synthesis of these two approaches to modeling

Survivorship bias in House Hunting: A practical modeling example using JAX

November 05, 2020 by Will Kurt

Survivorship bias is a very common topic when discussing statistics and data science, but identifying survivorship bias is much easier than modeling it! In this post we take a look at modeling survivorship bias in MLS house listing using mathematics, Python and JAX and see just how challenging of a task it is.

Learn Thompson Sampling by Building an Ad Auction!

September 28, 2020 by Will Kurt

Thompson sampling is a technique to solve multi-armed bandit problems but choosing actions based on the probability they offer the highest expected reward. In this post we learn about this technique by implementing an ad auction!

Why Bayesian Stats Needs Monte-Carlo Methods

August 16, 2020 by Will Kurt

Bayesian statistics rely heavily on Monte-Carlo methods. A common question that arises is “isn’t there an easier, analytical solution?” This post explores a bit more why this is by breaking down the analysis of a Bayesian A/B test and showing how tricky the analytical path is and exploring more of the mathematical logic of even trivial MC methods.

On Audre Lorde's "The Master's Tools..."

June 05, 2020 by Will Kurt

This is a very different post than the usual for this blog, but for this very reason it is important. I write about one of the paper’s that has had the biggest influence on me: Audre Lorde’s “The Master’s Tools Will Never Dismantle the Master’s House”.
