b)Compare the statistical properties of your multiplicative model with the linear model. Which fits the data better? Explain why.

c)In the multiplicative model perform a statistical test to determine whether demand is elastic, your competitor's product is a substitute, and if pies are a normal good at the 95 percent confidence level.

d)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.

e)Using the linear model, what is the expected value of next quarter's unit sales in the Los Angeles-Long Beach-Santa Ana, CA market?
