## mahal - Mahalanobis distance calculator

`mahalanobis` | Returns the distances of the observations from a reference set.

Mahalanobis distance calculator

Compute the Mahalanobis distance between observations and a reference set. The principle components of the reference set define the basis of the space for the observations. The simple Euclidean distance is used within this space.

bumps.dream.mahal.mahalanobis(Y, X)

  Returns the distances of the observations from a reference set.

  Observations are stored in rows Y and the reference set in X.
