Motivation While browsing Reddit’s r/DataIsBeautiful sub-reddit I came across a post from Fabio Votta showing a beeswarm plot of US County vote share in the 2020 Election. Having never seen a beeswarm plot before I wanted to come up with an excuse to try it out. As an NHL ...

The second ISL season wrapped up a couple of weeks ago, meaning that now we’re in the off-season. I loved watching the CBC’s coverage of the ISL. The races were exciting, the swimmers seemed like they were having a great time, they were absolutely...

With this blog post, I show how to use the mcbette R package in an informal way. A more formal introduction on mcbette can be found in the Journal of Open Source Science 1. After introducing a concrete problem, I will show how mcbette can be used...

“Mathematician John von Neumann is credited with figuring out how to take a p biased coin and “simulate” a fair coin. Simply flip the coin twice. If it comes up heads both times or tails both times, then flip it twice again. Eventually, you’ll get two different flips — either ...

For my ACT6100 weekly quiz, I usually generate some datasets, and then ask students to compare various predictive algorithms. Last week, it was about classification trees and random forests. And students were surprised to have such differences (they had to estimate the probability to have a specific label, for the ...

We’ve released the newest version of NIMBLE on CRAN and on our website. NIMBLE is a system for building and sharing analysis methods for statistical models, especially for hierarchical models and computationally-intensive methods (such as MCMC and SMC). We’ve released version 0.10.1.  Version 0.10.1 is primarily a bug fix release: –  ...

This blog is about getting corporate identity graphics ready in R using ggplot. Many corporates have decent identity Powerpoint decks and Excel templates available to work with, they might even have developed a PowerBI/Tableau...

This time the simple useless function will generate a long list of IF clauses that will in fact return the result of a mathematical operation between two numbers. This is not by no means any type of automatic generation of…Read more ›

rstudio::global(2021) will be a very different conference from previous years. We will miss being together physically, but we are enthusiastic about planning this free, virtual event designed to be inclusive of R users in every time zone. Even though ...

When what is not enough True, sometimes it’s vital to distinguish between different kinds of objects. Is that a car speeding towards me, in which case I’d better jump out of the way? Or is it a huge Doberman (in which case I’d probably do the same)?...

We’ve moved NIMBLE’s various sequential Monte Carlo (SMC) algorithms (bootstrap particle filter, auxiliary particle filter, ensemble Kalman filter, iterated filter2, and particle MCMC algorithms) to the new nimbleSMC package. So if you want to use any of these methods as of nimble version 0.10.0, please make sure to install ...

In the previous posts, I used popular machine learning algorithms to fit models to best predict MPG using the cars_19 dataset.  It was discovered that support vector machine produced the lowest RMSE.  In this post I am going to use XGBoost to...
