Fitting exponential curve with a step by step optimum grey derivatives background values

摘要：

In this paper, we put forward an approach fitting exponential curve, which firstly fitting first order linear differential equation, then obtain exponential curve. Fitting for the sequence, exponential curve plus the random error that under normal distribution, with step by step optimum grey derivatives background values, the results found by the proposed approach are compared with the results of approach that logarithm linearization, the comparisons show that the proposed approach comes with lower deviation, but the mean square error and average relative error is big.
