ABSTRACT
A stochastic process may be defined as a (possibly uncountable) indexed collection of random variables {Xt}, t ∈ T . The index set T usually represents time or space, and may be discrete or continuous. Whatever the case, we will at least assume T can be ordered (as can any subset ofRk). The central problem usually concerns the interaction of the dependence structure among the Xt with the index variable t.
