The Two Variable Linear Model
1.1
The Basic Linear Model
The goal of this section is to build a simple model for the non-exact relationship between
two variables Y and X , related by some economic theory. For example, consumption and
income, qua

More general tests of linear restrictions
In the previous chapter we have discussed how to test simple hypothesis involving linear constraints between the coecients of the model, based on `t'
