java - Find outliers in a group of double values -

i have list of double values , want find outliers in it. weka provide algorithm settle problem?

in work paper (first link), have full-text implementation of outlier algorithm weka.

also, algorithm used

proposed in paper, “a unified approach detecting spatial outliers”, s. shekhar et al. paper shows several spatial outlier detection tests. example, variogram-cloud displays data points related neighborhood relationships. each pair of locations, square-root of absolute difference between attribute values @ locations versus euclidean distance between locations plotted. in data sets exhibiting strong spatial dependence, variance in attribute differences data sets exhibiting strong spatial dependence, variance in attribute difference increase increasing distance between locations. locations near 1 another, large attribute differences, might indicate spatial outlier, though values @ both locations may appear reasonable when examining data set non-spatially. 1 major drawback of other outlier detection algorithms leads true spatial outliers being ignored , false spatial outliers being identified.

for algorithms outliers detection, may have @ siam tutorial.
