Figure 4 in Global phylogeny of Hadrosauridae (Dinosauria: Ornithopoda) using parsimony and Bayesian methods
Figure 4. Bayesian information criterion (BIC) plots resulting from the clustering model analysis implemented in Mclust (within the R statistical package). A, BIC plot of two clustering models for a one-dimensional data set (i.e. a character quantified with a linear measurement). B, BIC plot for various clustering models of NMMDS derived from a geodesic distance analysis (GDA) dissimilarity matrix. Indentifiers of clustering models indicate the type of distribution (spherical, diagonal, or ellipsoidal), volume (equal or variable), shape (equal or variable), and orientation (not applicable, coordinate axes, equal, or variable) of the clusters: EEE = ellipsoidal, equal volume, shape and orientation; EEI = diagonal, equal volume, variable shape; EEV = ellipsoidal, equal volume and shape, variable orientation; EII, spherical, equal volume and shape; EVI = diagonal, equal volume, variable shape; VEI = diagonal, variable volume, equal shape; VEV = ellipsoidal, variable volume, equal shape; VII, spherical, variable volume, equal shape; VVI = diagonal, variable volume and shape; VVV = ellipsoidal, variable volume and shape (Fraley & Raftery, 2003).
Figure 5 in Global phylogeny of Hadrosauridae (Dinosauria: Ornithopoda) using parsimony and Bayesian methods
Figure 5. Strict consensus tree of the 160 most parsimonious trees resulting from the parsimony analysis of 53 iguanodontian taxa. At each node, the pair of numbers separated by a slash above a branch represents, from left to right, a decay index and a bootstrap proportion. Bootstrap proportions lower than 50 are indicted by a hyphen. The decimal number in italics that appears below a branch represents the P value of topology-dependant permutation tail probability (T-PTP) analysis.
Figure 6 in Global phylogeny of Hadrosauridae (Dinosauria: Ornithopoda) using parsimony and Bayesian methods
Figure 6. Strict reduced consensus tree of the 160 most parsimonious trees resulting from the parsimony analysis of 53 iguanodontian taxa. Posterior to the analysis, Claosaurus agilis, Barsboldia sicinskii, and Nipponosaurus sachalinensis were pruned from the data after implementation of REDCON 3.0 (Wilkinson, 2001b). At each node, the pair of numbers separated by a slash above or below a branch represents, from left to right, a decay index and a bootstrap proportion. Bootstrap proportions lower than 50 are indicted by a hyphen. The decimal number in italics that appears below a branch represents the P value of topology-dependant permutation tail probability (T-PTP) analysis.
