Calculate the local continuity meta-criterion from a co-ranking matrix.

## Arguments

- Q
a co-ranking matrix

- K
vector of integers describing neighborhood size

## Value

A number, the local continuity meta-criterion

## Details

The local continuity meta-criterion (Chen and Buja, 2006) is defined as
$$ LCMC = \frac{K}{1-N} +
\frac{1}{NK} \sum_{(k,l)\in U L_K} q_{kl} $$
Higher values mean a better performance of the dimensionality reduction.
