"WebDec 1, 2004 · Step 1 is to estimate the leading genetic and environmental principal components. With k traits, we search a k -dimensional space for the first genetic PC, ψA1, and for the first environmental PC, ψE1. The search continues until we converge on estimates of ψA1 and ψE1 that optimize the fit ( Figure 1B ). " - Principal component analysis of genetic data
