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

1 |

`Q` |
a co-ranking matrix |

`K` |
vector of integers describing neighborhood size |

The local continuity meta-criterion (Chen and Buja, 2006) is defined as

* LCMC = \frac{K}{1-N} +
\frac{1}{NK} ∑_{(k,l)\in U L_K} q_{kl} *

Higher values mean a better performance of the dimensionality reduction.
