In the last article of the current year, we will examine and compare some of the tree algorithms for the classification. The dataset we are going to use for this will be the answers given to the loan applicants and their evaluated features for it. The first algorithm we will ...

It is almost the beginning of a new year and I have decided to finish off this year with a quick blog post. Also, friends were shaming me that I have been slacking off on this blog lately. Therefore, let’s get started right away. We’ll keep things simple ...

In this post, we will look at running two programs that infer population history — understood as changes in linkage disequilibrium over time — from genotype data. The post will chronicle running them on some simulated data; it will be light on theory, and light on methods evaluation. Linkage disequilibrium, i.e. ...

Nina Zumel Recently, we’ve been reading about a new correlation coefficient, \(\xi\) (“xi”), which was introduced by Professor Sourav Chatterjee in his paper, “A New Coefficient of Correlation”. The \(\xi\) coefficient has the following properties: If \(y\) is a function of \(x\), then \(\xi\) goes to 1 asymptotically as \(n\) […]

A brief tutorial encompasing the use of PCA Maker, a web application in R made with Shiny.   The purpose of this post is present a brief tutorial about how to install and use PCA Maker. Some concepts about PCA are covered in other posts on this blog...

Frequentist statistical methods, despite their flaws, are generally serviceable for a large suite of practical problems faced by engineers during product development of medical devices. But even in domains where simple models usually do the trick, there remain instances where a Bayesian approach is the best (and perhaps only logical) ...

In my previous post I looked at College Football Non-Conference games to create a network map overlaid on top of the United States using the {ggraph} package. In this post I’ll be extending that to examine Conference Realignment, which is when colleges change from one conference to the next. ...
