| Abstract: | Aiming at the influence of the gross error to the estimated value of the parameter, when determining the undetermined parameters in the negative exponential function using weighted least square method, the paper presents the robust solution of the undetermined parameters. Also, using case histories, it proves the effectiveness of this method. |
