Introduction
In the previous chapter it was generally assumed that the demand function for a firm or market was known; in practice it has to be estimated from empirical data, and that is the subject of this chapter. When we speak of estimation there are a number of stages involved in this process. Some of these stages may be omitted in the simpler methods of estimation, like the first two described in the next section.
