public class CovFMMCallCenterStat
Represents a set of probes that collect covariances in matrices of functions
of multiple means tallies. An instance of this class is constructed using a
CallCenterStatProbes
object. For each matrix of functions of multiple
means tallies defined in the inner set of probes, this class can extract the
covariance matrix of the functions' domain, and add these covariances into
matrices of tallies. This results in averages of covariances which are useful
for estimating the variance of stratified estimators.
More specifically, let
∈
be a vector used to compute the
function associated with position (r, c) in a matrix of performance
measures m. Let
be the matrix of covariances of

We suppose that
