DeltaX, a market research firm located in Cleveland, conducts various market research for pharmaceutical and medical device manufacturers. In one of its research projects, DeltaX wanted to apply the Bass Model to predict the diffusion of a new drug that treats Alzheimer's Disease. The drug has not been launched so there is no sales data. To use the Bass model for prediction, DeltaX needs to first estimate the Bass model parameters m, p and q.

Answer the following questions:

(1)What do m, p and q represent in the Bass model?

(2)Briefly describe how DeltaX should estimate parameters p and q.
