Computes the odds of correct classification (OCC) for each cluster. In other words, it computes the proportion of trajectories that can be expected to be correctly classified by the model for each cluster.

OCC(object)

Arguments

object

The model, of type lcModel.

Value

The OCC per cluster, as a numeric vector of length nClusters(object). Empty clusters will output NA.

Details

An OCC of 1 indicates that the cluster assignment is no better than by random chance.
