## Sensitivity of odds-ratios calculated on dichotomized variables to inclusion criteria

A short simulation example showing why dichomization of continuous variables can lead to wrong conclusions.

## Creating a bookdown book with the bs4 theme

A short guide to creating a bookdown book using the bs4 theme

## What is Gradient Descent? (Part I)

Exploring gradient descent using R and a minimal amount of mathematics

## Statistical simulation of robust estimators with tidyverse tools

Tidyverse tools provide a powerful way to do statistical simulations. We demonstrate this approach by evaluating the properties of the mean and median as estimators of center for two distributions.

## Using gganimate with ggmap

Combining gganimate with ggmap can be used to create animations of geographic data. I give a few examples using data from Nashville Open Data.

## Repeated testing inflates type I error

Type I error is increased when you test your hypothesis multiple times during the data collection process. Simulations can provide a clear picture of this process.

## What is a statistic?

Exploring the idea of a statistic by simulating dice rolls in R
