Multivariate wrapped Gaussian

Figure 5. Thermal - (radians) scatterplots for terminally blocked valine at T = 0.2 kcal/ mol (a, d), 0.6 kcal/mol (b, e), and 2.2 kcal/mol (c,f) and the corresponding descriptions produced by the angular linear quasi-harmonic (a-c) and multivariate wrapped Gaussian (d-f) models. The shaded regions are bounded by the contours where ( , )/ ( 0, °) = e 2. In contrast to the quasi-harmonic method, the MWG method accurately models the data set even at high temperatures.
