* ResponseStatisticModelEvaluator is an implementation of

* and provides additional response functions that are statistics of
* some other stochastic response. Since it is designed to support
* derivatives w.r.t. the PCE coefficients of the parameters, the underlying
* model evaluator should be a block model evaluator.
