2
3Description::
4After forming one or more function train approximations, this
5tolerance is used for rolling up final results, in particular,
6combining multilevel/multifidelity expansions and forming products for
7higher-order moment estimation.  It is generally intended as a looser
8tolerance than \c rounding_tolerance.
