    We consider a slight perturbation of the Hull-White short rate model and the resulting forward rate equation. We identify the model coefficients by using the martingale property of the normalized bond price. The forward rate and the system parameters are then estimated by infinite dimensional Kalman filtering equations, coupled with the usual statistical techniques.
