Abstract From the Canadian patent

Abstract A method for analyzing data modeled by a sum of exponential terms by determining weighted moments of a characteristic independent variable and amplitude for such data. In a specific embodiment, weighted moments of time and intensity are determined from the data. Corresponding weighted moments of time and intensity are also determined for a model consisting of a sum of exponential terms. Corresponding weighted data moments and modeled moments of time are equated and corresponding weighted data moments and modeled moments of intensity are equated. The resulting set of equations is solved simultaneously for the values of the time and intensity parameters which appear in the model.
