I know there are different reasons for choosing a particular model (e.g. log log, semi log, lin log).
I read somewhere that the semi log (where only the log of Y is taken) corresponds to a multiplicative/additive relationship.
My dependent variable are market shares which growths/operates multiplicatively (I believe) and most of my independent variables are dummies & some variables are related to culture (which is expected to change slowly).
I am not sure if these reasons are good/strong enough for choosing a semi log model?
Also how would you interpret dummy variables in a semi log regression where only the logarithm of Y is taken?
