adegenet.r-forge.r-project.orgUsual approaches such as Principal Component Analysis (PCA) or Principal Coordinates Analysis (PCoA / MDS) focus on VAR(X). That is, they only describe the global diversity, possibly overlooking di erences between groups. On the contrary, DAPC optimizes B(X) while minimizing W(X): it seeks synthetic variables, the discriminant functions, which show
A Tutorial on Principal Component Analysis
www.cs.cmu.eduPrincipal component analysis (PCA) is a mainstay of modern data analysis - a black box that is widely used but poorly understood. The goal of this paper is to dispel the magic behind this black box. This tutorial focuses on building a solid intuition for how and why principal component
