Hi all, I am using the Zelig package in R with a log-log regression model similar to the following: z.out <- zelig(lnDONATIONS ~ lnPRICE + lnFUNDRAISING + lnAGE, model = "ls", data = mydata) x.out <- setx(z.out) s.out <- sim(z.out, x = x.out) summary(s.out) plot(s.out) This works fine, but I am trying to implement something that is allowed in the Stata-based precursor to Zelig (_clarify_); specifically, in the _clarify_ package, after the 'setx' command, you can type in **simqi, tfunc(exp)** in order to get the expected values based on the exponential transformation of the dependent variable (the _simqi_ command in Stata is analogous to the _sim_ comamnd in R/Zelig). My question is, can this post-_setx_ exponential transformation be done in R with the Zelig package, and if so, how? The very extensive Zelig documentation does not seem to have an analogue to the 'tfunc' command in the _clarify_ package. Thanks in advance for any insights.
