Procrustes orthogonal

WebbThe function procrustes (A,B) uses the svd decomposition to find an orthogonal matrix Q such that A-B*Q has a minimal Frobenius norm, where this norm for a matrix C is defined as sqrt (Trace (t (C)*C)), or norm (C,'F') in R. Solving it with B=I means finding a nearest orthogonal matrix. WebbBiplot analysis map the departments as object and courses as variable. The result of this study shows that the changes of curriculum which were applied to class of 2011/2012 increase the academic achievement of IPB department’s. Procrustes analysis shows that the biplot of the class of 2010/2011 and 2011/2012 configuration have a 67.4% ...
