What are the consequences of this correlation between x and u? Now higher levels of x have two effects on y. From (4.43) there is both a direct effect via x and an indirect effect via u effecting x which in turn effects y. The goal of regression is to estimate only the rst effect, yielding an estimate of .

As mentioned in chapter14, multiple measurements per subject generally result in the correlated errors that are explicitly forbidden by the assumptions of standard (between-subjects) AN(C)OVA and regression models.
