marginally significantp = 0.08
A wilcoxon signed rank test on residuals indicates that asterids I are marginally significant ( p = 0.08) for lacking diversity (two sided, μ = 0) but other groups (gymnosperms, p = 0.25; magnoliids, p = 0.20; rosids I, p = 0.97; rosids II, p = 0.63; asterids II, p = 0.63) show no detectable biases in diversity.
