The documentation of the elbow package suggests this is based on the reference Thorndike 1953:
|
@details Implementation based on paper @cite article::cluster::elbow::1. |
|
@article{article::cluster::elbow::1, |
|
author = "Thorndike, Robert L.", |
|
title = "Who belongs in the family?", |
|
journal = "Psychometrika", |
|
year = "1953", |
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?
