Where;
K = Subpopulations;
Ln (PD) = The log likelihood for each K;
L (K) = An average of 20 values of Ln P(D);
stdev = Standard deviation for 20 values of Ln P(D);
L’(K) = L(K) _n – L(K) _n-1;
L”(K) = L′(K) n_+ 1 − L′(K);
∆K = |L”(K)|/Stdev;
The gray color of the third line designates the optimal sub-populations of the panel based on the highest delta K value
