Improved prediction model of modified exponential curve

Exponential curve prediction model is one of the most common prediction models[1]. This paper is mainly introduce improved model which add one-time items based on modified exponential curve prediction model. In this article, we not only proved the characteristics of the historical data which consistent with this model in theory but also describes how to solve the unknown parameters according to the given time series. Improved model overcomes the shortcomings of modified exponential curve prediction model which is only a monotonic function model. So the improved model has more extensive application value. Then, we promoted the conclusions at last.
