Decision Criteria by Class Solution for LCGA Models Youth Followed Ten Years after Treatment

Classes Adjusted BIC Entropy BLRT (p-value) Range of maximum probabilities of class membership
3 24021 .998 <.001 .972 − .999
4 21790 .999 <.001 .999 +
5 20829 .997 <.001 .672 −.999
6 20076 .998 <.001 .957 − .999
7 19505 .996 <.001 .618 − .999
8 19018 .999 <.001 .935 − .999
9 18593 .994 <.001 .778 −.999

Note: Range of maximum probabilities of group membership for the 4 class solution had a range of .999 and above suggesting overfit.
