condMom
compute moments of conditional distribution of ith element of normal given
all others.
condMom(x, mu, sigi, i)
vector of values to condition on - ith element not used
length(x) mean vector
length(x) dim inverse of covariance matrix
conditional distribution of ith element
a list containing:
cond mean
cond variance
This routine is a utility routine that does not check the input arguments for proper dimensions and type.

computes moments of
