WebbProcrustes analysis 136 uses dimensionally reduced data to test whether patterns (distances) between samples in one data set are observed in the other, essentially correlating ordination spaces ... WebbCollectively these may be regarded as m configurations, or scalings, each of n points in p -dimensions. The problem is investigated of translating, rotating, reflecting and scaling the m configurations to minimize the goodness-of-fit criterion Σ m i=1 Σ n i=1 Δ 2 ( P (i) j G i ), where G i is the centroid of the m points P (i) i ( i = 1, 2 ...

Next we freeze the triangle T00to be the baseline to which we compare the other one. We look for the optimal rotation of the triangle Te00so that it is as close as possible to the baseline triangle T00.
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. A Procrustean bed is an arbitrary standard to which exact conformity is forced. • In Edgar Allan Poe's influential crime story "The Purloined Letter" (1844), the private detective Dupin uses the metaphor of a Procrustean bed to describe the Parisian police's overly rigid method of looking for clues. • French philosopher Jacques Derrida, in "The Purveyor of Truth", his response to Jacques Lacan's s…
