The exploratory outlier analysis chart allows:
The chart can be generated based on either Mahalanobis distance or jackknifed Mahalanobis distance.
The outlier chart on this page was plotted from a wireline log data set with 2055 object. The outlier threshold was defined at chi-squared=97.5%; the data below the outlier threshold were classified into three zones based on the range of Mahalanobis distance from the multivariate mean.
