High Quality Content by WIKIPEDIA articles! In statistics, a varimax rotation is a change of coordinates used in principal component analysis and factor analysis that maximizes the sum of the variances of the squared loadings. That is, it seeks a basis that most economically represents each individual so that each individual can be well described by a linear combination of only a few basis functions. Suggested by Henry Felix Kaiser in 1958, it is a popular scheme for orthogonal rotation which cleans up the factors as follows: "for each factor, high loadings will result for a few variables; the rest will be near zero.
