which is the ''average local reachability density of the neighbors'' divided by the object's own local reachability density. A value of approximately {{math|1}} indicates that the object is comparable to its neighbors (and thus not an outlier). A value below {{math|1}} indicates a denser region (which would be an inlier), while values significantly larger than {{math|1}} indicate outliers. |
