Figure 3From: A simple procedure for the comparison of covariance matricesExamples of population samples used in the simulations (two variables case, size = 100): (a) from the reference population, (b) from the population resulting in a covariance matrix with changed orientation, (c) from the population resulting in a covariance matrix with changed shape, and (d) from the population resulting in a covariance matrix with both orientation and shape changed. Each axis in the graphs corresponds to one of the two variables.Back to article page
