Shape based assignment tests suggest transgressive phenotypes in natural sculpin hybrids (Teleostei, Scorpaeniformes, Cottidae)

Table 2 Jackknife estimates of assignment performance.

Jackknife test of assignment. Percent correct and false assignments when fractions of 1% to 80% of the specimens are left out in the CVA procedure and then assigned to groups in the remaining dataset. Large fractions of the data can be removed without loss of the discriminatory power of CVA axes.
