arithm of the mean using a linear model. Thus, we take logs calculating i = log( i) and assume that the transformed mean follows a linear model i= x0 i :Thus, we consider a generalized linear model with link log. Com-bining these two steps in one we can write the log-linear model as log( i) = x0 i : (4.2) In this model the regression coe cient
