A numerical solution of multivariate normal integrals over a region B is given where the covariance matrix is the sum of a diagonal matrix D and the product of a row vector with its transpose. An ...

A systematic study of quadrature formulae for the Wiener integral ∫ F [ x ] w(dx) of the type ∫ F [ θ (u, ·) ] ν(du) is presented. The Cameron and Vladimirov quadrature formulae, which are the ...
