The Statistical Analysis of a Certain Kind of Sales Diffusion Model

Shu LIANG, Xiaoling XU, Beiqing GU


The essay works out MLE (Maximum Likelihood Estimation) of probability model parameter about the third sales diffusion curve given by ZHENG Zukang and researches the existence of the estimation. Besides, this essay inspects the accuracy of the estimation via Monte Carlo simulation and throws light on methods of essay by simulated data.

Key words: Sales diffusion model; Maximum Likelihood Estimation; Monte Carlo simulation


Sales diffusion model; Maximum Likelihood Estimation; Monte Carlo simulation
