摘要
基于BASS模型,对3M公司历年来汽车相关产品销售历史数据利用非线性最小二乘法拟合扩散系数和创新系数。通过对扩散系数和创新系数的分布特性的研究,发现3M公司不同类别新产品有各自类似的市场扩散特性。
Based on BASS model, the innovation factor and diffusion factor are obtained respectively with the nonlinear least square regression from the historical automobile products sales data of 3M, which shows the inclination of different product series. Using these factors, the future sales volume can be predicted.
