Two major issues associated with model validation are addressed here. First, we present a maximum likelihood approach … to define and evaluate a model validation metric. The advantage of this approach is it is more easily applied to … effect of this on model validation metrics. We show that ignoring correlation in multivariate data can lead to misleading …
