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.

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!
