Employ a nodal sparse grid construction in stochastic collocation
Alias: none
Argument(s): none
Default: nodal
Stochastic collocation with sparse grids can employ either a nodal or hierarchical formulation. The nodal formulation does not require nested interpolation rules and is therefore more generally applicable. However, in the context of adaptive refinement, it can suffer from loss of precision due to subtractive cancellation.
