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 L 2 sense of order ε2 to the best nonlinear filter. The technique involves the use of an efficient linearization method obtained via the Girsanov transformation
