What is (are) the significance (implications) of Mahalanobis distance from self having mean different from 1?

26 February 2016 1 4K Report

The Mahalanobis distance of data from itself is, by definition 1. However, with certain data sets, I get values like 1.3 and 1.5, which I am unable to understand. What would be a possible explanation for obtaining such values?

David Eugene Booth

Can you give more information about when this happened? Why wouldn't it be zero instead of 1?
