First, the relationship between two approximations to the same function, but using different points of approximations is examined and it is demonstrated that changing the point of approximation does not alter the predicted values of the approximation.
Multivariate Statistics: High-Dimensional and Large-Sample Approximations is the first book of its kind to explore how classical multivariate methods can be revised and used in place of conventional statistical tools.
Beginning with chapter 21, they offer examples of multivariate approximations; randomized setting, average case setting, and worst case setting for multivariate approximations and linear problems; nonlinear problems; and power of function values for multivariate approximations.

His topics include multivariate modulated Markov log-price processes, backward recurrence reward algorithms, the convergence of option rewards, space-skeleton reward approximations, and the convergence of tree-type reward approximations.
There is also an interesting "symmetry" with respect to the CG approximations showing that they are in a sense equivalent.
