概要	This paper proposes a new weighted additive model for the whole demand analysis of a seasonally dependent product, i.e., Japanese beer, using meteorological and regional data, considering “regional characteristics of climate” and “regional homogeneity of demand together,” with the further addition of social customs factors, policy factors, and a demand trend. Using the alternating least squares method, we attempt parameter estimation for the model with an inseparable parameter group generated by expressing “regional characteristics of climate” and “regional homogeneity of demand” together as a product of mutually independent factors (meteorological and regional factors). The results show that the proposed model is valid and provides insight into the effects of the factors influencing demand.
