Thresher-package: Threshing and Reaping for Principal Components

Description Details Author(s) References See Also


The Thresher package defines classes used to identify outliers (threshing) and to compute the number of significant principal components and number of clusters (reaping) in a joint application of PCA and model-based clustering.

Standard usage is to apply the Thresher function to a data set in order to estimate the principal component dimension and identifty outliers. You then apply the Reaper function to actually remove the outliers and assign the remaining objects to clusters.
