When the fast processes of a continuous system are modeled by white noise--as is common for physical applications--the resulting stochastic model converges to a Stratonovich stochastic differential equation (Wong and Zakai 1965; Papanicolaou and Kohler 1974; Gardiner 1985; Penland 2003a,b).
Objective: Some of the most important and exciting challenges of our information age have led to the development of novel statistical methodology and algorithms that are designed to deal with inference settings involving high-dimensionality, graphical and network structures, inverse problems, big data, stochastic differential equations, diffusion processes, cosmic microwave background maps, brain tomography etc.
