|b In this paper, we analyze the density functions of R2 and the adjusted R2 (R-2 ) when there are two types of misspecification. The first is the exclusion of relevant variables and the other is the inclusion of irrelevant variables. It is shown numerically that both R2 and R-2 tends to underestimate when there are omitted variables, and both tend to overestimate when there are irrelevant variables.
