WebbFunction protest uses a correlation-like statistic derived from the symmetric Procrustes sum of squares ss ss as r =\sqrt {1-ss} r = 1−ss, and also prints the sum of squares of the symmetric analysis, sometimes called m_ {12}^2 m122. Function protest has own print method, but otherwise uses procrustes methods.
