calcPurity | R Documentation |
Calculates purity for liger
clustering and external clustering (true clusters/classes).
Purity can sometimes be a more useful metric when the clustering to be tested contains more
subgroups or clusters than the true clusters (or classes). Purity also ranges from 0 to 1,
with a score of 1 representing a pure, or accurate, clustering.
