Demand forecasting model of automobile profit-making ability

摘要

A double forecasting model based on conditional expectation was proposed through probability distribution of demand o fautomobile profit-making ability. The demand of automobile profit-making ability is the sum of all compound variables which indicated tha tautomobile profit-making ability was credited to customer occurring in a certain period of time. Probability distribution o f automobile profit-making ability was acquired using throughout probability theory. In view of such a fact, demand of automobile profit-making ability can be viewed as an conditional mathematic expectation The forecasting model is proposed using growing function. Theoretical analysis and Case study shows that model based on conditional expectation is better than other model available with respect to forecasting demand of automobile profit-making ability.
