What are Mahalanobis Distances

What about looking at outliers statistically in multiple dimensions? There is a multi-dimensional version of the z-score - Mahalanobis distances! Let's see how we can use those to look at anomalies, all in under 5 minutes.

This is what UA-cam should be. No fluff, informative, and entertaining. Thank you Doc!

Thank you sir

awesome video. Question, is the Mahalanobis distance used with one variable from two different classes or two variables of the same class?

[@AricLaBarr]

Not suer exactly what you are asking. However, we look at any number of continuous variables to calculate Mahalanobis distances. I used 2 just so we could visualize them easily!
