  • Abstract
    A study is made of the nonlinear filtering of diffusions when the observation noise covariance is proportional to ε2, a small parameter. It is shown that the suboptimal solution obtained by the extended Kalman filter is an approximation in the L2 sense of order ε2 to the best nonlinear filter. The technique involves the use of an efficient linearization method obtained via the Girsanov transformation
