Use Leave-One-Out error rate as the Fitness function
Check this option to compute a leave-one-out error rate after each model fit, and use it as the fitness function for the genetic algorithm.
If this option is left unchecked , the average squared error based on posterior probabilities is used as the fitness function.
Caution : Checking this option can substantially increase computing time.
