What I did with -glm- is largely but not exactly similar to what you are doing. I am modeling the mean wage which is linked to the predictor variables through a log function, while you are modeling the mean log(wage). The former is probably closer to what you really want to do. Another way of thinking about the difference between these two models is that you are modeling the geometric mean of wage, while I am modelling the arithmatic mean of wage. See: Roger Newson (2003) Stata Tip 1: The eform() option of regress. The Stata Journal, 3(4): 445. http://www.stata-journal.com/article.html?article=st0054 > A multivariate analysis via odd ratios is then a better resolution, i > presume, or? No. I said that there is a peculiarity in my sub-sub-discipline, which makes it unnecesary for me to transform the factor change (exp[b]) into percentage change (100*{1-exp[b]}). This peculiarity is that people in my sub-sub-discpline are used to interpreting a very similar statistic, the odds ratios. -- Maarten ----------------------------------------- Maarten L.
