Homoscedasticity What is homoscedasticity? To me, it is a fancy word to describe how data has the same variance over its residuals. In other words, it is the state of relatively constant variance over the data’s distribution. In this week’s post we are going to take a look at what exactly that means and what it might look like. As usual, we s...
