Principal Component Analysis, Second Edition
cda.psych.uiuc.eduThe section on non-normal data includes independent compo-nent analysis (ICA), and the section on three-mode analysis also discusses techniques for three or more groups of variables. The penultimate section ... Principal component analysis is probably the oldest and best known of the techniques of multivariate analysis. It was first introduced ...

The second principal component is the direction which ... “assume the different rows of the data frame are statistically independent”. This is because no such assumption is required for principal components. All it does is say

www.cs.helsinki.fiIndependent component analysis (ICA) is a recently developed method in which the goal is to fin d a linear representation of nongaussian data so that the components are statistically independent, or as independent as possible.
Independent Component Analysis (ICA)
sci.utah.eduindependent components; as they are random variables, the most natural way to do this is to assume that each has unit variance: E{s i 2}= 1. Note that this still leaves the ambiguity of the sign: we could multiply the an independent component by −1 without affecting the model. This ambiguity is, fortunately, insignificant in most applications.
Principal Component Analysis - Department of Statistics
www.stat.columbia.eduPrincipal Component Analysis The central idea of principal component analysis (PCA) is to reduce the dimensionality of a data set consisting of a large number of interrelated variables, while retaining as much as possible of the variation present in the data set. This is achieved by transforming to a new set of variables,
