Computes the Rand Index and the Adjusted Rand Index between two partitions
RandIndex(Partition1, Partition2)
Vector describing the first partition
Vector describing the second partition
List of following components:
Rand Index between the partitions
Adjusted rand Index between the partitions
Supports incomplete partitions (value 0 is coding for missing stimulus)
