NNAN computes, for each set of points, the nearest neighbor
in n-dimensional space, and the distance to this neighbor.

OREG calculates the orthogonalized regression of one or
more dependent variables on the principal components of up
to 20 regression variables.

OREH, an auxiliary program to OREG, adds the corresponding
orthogonaIized regression coefficients for nominated com-
ponents to give a single vector of standardized regression
coefficients.
