A genealogical interpretation of principal components analysis.

PLoS genetics - 1 Oct 2009

McVean Gil

Abstract excerpt

Principal components analysis, PCA, is a statistical method commonly used in population genetics to identify structure in the distribution of genetic variation across geographical location and ethnic background. However, while the method is often used to inform about historical demographic proces...
