摘要：Based on the second type of sales diffusion curve proposed by the professor Zheng Zukang, the existence of the moment estimation is demonstrated through researching the digital characteristics of parameters in the model. Besides, the moment estimations of parameters are calculated. The precision of estimation is investigated by Monte-Carlo simulation, and some examples are used to validate this model. Key words: Impulse purchase behavior; Sales diffusion; Moment estimation; Monte-Carlo simulation
