Reference for the "Elbow length" method?
kno10 opened this issue · comments
The documentation of the elbow package suggests this is based on the reference Thorndike 1953:
pyclustering/docs/citation.bib
Lines 552 to 556 in bf4f51a
Yet, I cannot find the "Elbow length" equation used in this reference, in fact he appears very skeptical that such elbows can be reliably identified (for a good reason...).
Is there another reference for this particular method?
