In a previous post I explored the correlations between measurements in the ANSUR-II dataset, which includes 93 measurements from a sample of U.S. military personnel. I found that measurements of the head were weakly correlated with measurements from other parts of the body – and in particular the protrusion of the ears is almost entirely uncorrelated with anything else.
Meep, you’re teasing us with the conclusions about body parts without sharing some data.
I took the male only data, chose a few of the 93 measurements, and calculated correlation coefficients. I did not use PCA, but I selected the variables in the author’s principal component 6 about the head, and I added the last variable for fun:
