Lof scores
WitrynaA LOF score of approximately 1 indicates that density around the point is comparable to its neighbors. Scores significantly larger than 1 indicate outliers. The default threshold of 0.025 will classify as outliers the observations located at qnorm(1-0.025) * SD) of the log-transformed LOF distance.

WitrynaA LOF score of approximately 1 indicates that the lrd around the point is comparable to the lrd of its neighbors and that the point is not an outlier. Points that have a substantially lower lrd than their neighbors are considered outliers and produce scores significantly larger than 1. If a data matrix is specified, then Euclidean distances and ...
