Dear all,

I have a question regarding marginal data densities of DSGE model. When using Dynare_v3, sometimes I end up with positive log(P(Y|model_i)) and sometimes negtive log(p(Y|model)). I am wondering if the positive log marginal data densities is always the one we prefer and is it possible to compare a positive log(p(Y|model)) to the negtive log(p(Y|model)? Thanks!
