[source]
(cached attribute) dffits measure for influence of an observation
based on resid_studentized_external, uses results from leaveoneobservationout loop
It is recommended that observations with dffits large than a threshold of 2 sqrt{k / n} where k is the number of parameters, should be investigated.
