Applying the EKF to stochastic differential equations with level effects. (English) Zbl 0982.93070

The authors consider a nonlinear filtering problem for a model with multiplicative noise. For a restricted class of systems of stochastic differential equations, they propose a transformation such that the transformed system is a system with additive noise.
