In a log-linear model, a unit-change in the independentvariable X (i.e., DeltaX=1)is associated with a 100*Beta%change in Y.This is one possible way of interpreting such a model. Analternative way is discussed in: Roger Newson (2003) "StataTip 1: The eform() option with regress" The Stata Journal,3(4): 445.http://www.stata-journal.com/article.html?article=st0054Both interpretations are correct, they are just different ways of looking at the same model.
