An econometric model is the combination of mathematical, statistical, and economic concept that represents the mathematical estimate of the variables or parameters there in the identified model. This approach, however, ultimately estimates characteristics of the joint population density of x and y, f(x,y), or objects that can be derived from it, such as: Ch.
