WebPCA in a nutshell Notation I x is a vector of p random variables I k is a vector of p constants I 0 k x = P p j=1 kjx j Procedural description I Find linear function of x, 0 1x with maximum variance. I Next nd another linear function of x, 0 2x, uncorrelated with 0 1x maximum variance. I Iterate. Goal It is hoped, in general, that most of the variation in x will be WebPCA analysis in Dash Dash is the best way to build analytical apps in Python using Plotly figures.
