摘  要:
In the paper, a mutual division method for parameter estimating was put forward, in which the data don't need to be preprocessed and the generations of accumulate plus and subtract don't need to be made. The method can be used for model establishing on equal interval, as well as on non interval. Besides that, a function transform method for parameter estimating of GM(1,1) was also established. The examples of data processing by both the mutual division and the function transform methods were given, and their fitting accuracies were satisfied. The results from the examples showed that the both methods were simple and practical and had a generalizing value in the field of CAD.
