Orthogonal expansions of the nonlinear functionals of the Gaussian process and their application to statistical analysis
M. E. Shaikin · Automation and Remote Control · 2007
Orthogonal expansion of the space of quadratically integrable nonlinear functionals of the Gaussian random process was considered. The problem of explicit construction of the expansion terms was restated as generation of the differential equations for its coordinate functions. The method of canonical expansions from the linear statistical analysis was generalized to the nonlinear case on the basis of the results obtained.
