2. Estimate a multiplicative demand function for the San Francisco Bread Co. Report your parameter estimates and regression statistics for the multiplicative model.
4. Describe the statistical significance of each of the independent variables included in the San Francisco Bread Company multiplicative demand equation. Interpret the coefficient of determination and F statistic for the multiplicative model.

What is your estimate of the price elasticity of demand, advertising elasticity of demand, income elasticity of demand, and cross-price elasticity of demand in the multiplicative model? Compare these elasticity estimates with the corresponding elasticities in the linear model when calculated at mean values for each variable.
