What are the principal components in a 3D Biplot after k-means clustering?
Hi, I have clustered a dataset with n=5008 using the kmeans clustering algorithm. One option for a visualization is the 3D biplot that uses 3 axes with the principal components. Unfortunately, I can not find a clear explanation where it comes from. My guess is, that simply the variables used for clustering are used for a principal component analysis, but i have no proof. Thank you for your help!Se...
