public class LMDiagnostics extends Object
DFFITS is a diagnostic meant to show how influential a point is in a statistical regression. It is defined as the change, in the predicted value for a point, obtained when that point is left out of the regression, "studentized" by dividing by the estimated standard deviation of the fit at that point.
Cook's distance is a commonly used estimate of the influence of a data point. Cook's distance can be used in several ways: to indicate data points that are particularly worth checking for validity; to indicate regions of the design space where it would be good to be able obtain more data points.
Hadi proposed a measure of influence of the ith observation based on the fact that influential observations are outliers in either the response variable or in the predictors, or both.
