The distance between data1
This distance is computed as:
distance( x, y ) = sum ( xi - yi )^2
Squaring the simple Euclidean distance places progressively greater
weight on objects that are further apart.
Missing values are allowed. Pairs of elements are excluded from the
distance measure when their comparison returns NaN. If all pairs are
excluded, NaN is returned for the distance measure.
