Table 6. Jackknifed classification matrix.

The Jackknifed classification matrix indicates how many corallites were correctly classified by groupings based on regions (e.g., 95% of P. evermanni corallites were classified correctly). The eigen values indicate that the first two factors account for the largest portion of the variance.

	Eeaster Island	Fiji	Galapagos	Tahiti	P. evermanni	% correct
Easter Island	26	2	5	4	3	65
