Figure 4
Posterior predictive check of the multivariate model using three (a) and 48 (b) observation pairs. Each joint posterior distribution is represented by a set of 95% isodensity ellipses (additive blue) from the MCMC trace. The coordinates of the centre correspond to the posterior samples of F₁² and F₂² (red circles). The length and direction of the ellipse axes are determined from the eigendecomposition (SciPy library function) of the covariance matrix of each MCMC trace sample. Blue crosses indicate the observations.
