tl;dr Choosing the appropriate dashboarding/reporting/BI tool has never harder than it is now, as there are plenty of genuinely great options such as R Shiny, PowerBI, and Tableau. Today we’ll compare two widely used tools at Fortune 500 companies: PowerBI – a collection of software services, apps, and ...

Introduction We’ve been writing on the distribution density shapes expected for probability models in ROC (receiver operator characteristic) plots, double density plots, and normal/logit-normal densities frameworks. I thought I would re-approach the issue with a specific family of examples. Definitions Let’s define a “probability model” as a ...

This is the latest in my series of screencasts demonstrating how to use the tidymodels packages, from starting out with first modeling steps to tuning more complex models. Today’s screencast walks through how to tune, fit, and predict from deci...

When preparing my mid-term exam for my undergrad mathematical statistics course, I wanted to use the inverse Gaussian distribution IG(μ,λ) as an example of exponential family and include a random generator question. As shown above by a Fortran computer code from Michael, Schucany and Haas, a simple version can be ...

A rather boring episode of The Bachelorette can be made more interesting by looking at the data surrounding those who follow it.

The double density plot contains a lot of useful information. This is a plot that shows the distribution of a continuous model score, conditioned on the binary categorical outcome to be predicted. As with most density plots: the y-axis is an abstract quantity called density picked such that the area […]

I’ve done an experiment regarding package downloads from CRAN (or the RStudio CRAN mirror at least) and now it’s time to share the results. When the first version (0.0.1.0) of SwimmeR was released on CRAN in October of 2019 it had very few features - just a couple functions for ...
