Table 2.

P values from permutation resampling (10000 replicates) for Procrustes distances among groups (upper triangle) and from the mean shape tests of 2 consecutive ages by using a modified Hotelling T-squared statistic¹based on permutation resampling (5000 replicates; lower triangle). In both cases, groups that are notsignificantly different from each other at P < 0.05 are bolded. The non significance of the P3–P7 and P7–P14 mean shape differences are most likely due to the low power of the T-squared statistic, given the small sample sizes (8 and 6, respectively) and the variation among the samples at these ages.
