[amelia] calculating degrees of freedom, t-stat, and f-values

Hi, I am a novice user of Amelia, and I am puzzled on how I can obtain the degrees of freedom, t-statistic, and f-values of combined multiply imputed data using Amelia or Zelig. To understand how to combine imputations, I used code straight from the Amelia manual. When I loaded Zelig and used the zelig function, I get coefficients that appear to be coefficients of individual imputations, and not those of the combined set. The code I used was: z.out.imp <- zelig(tariff ~ polity + pop + gdp.pc + year + country, data = a.out$imputations, model = "ls") summary(z.out.imp) Furthermore, I have also tried this code: + ols.out <- lm(tariff ~ polity + pop + gdp.pc, data = a.out$imputations[[i]]) + b.out <- rbind(b.out, ols.out$coef) + se.out <-rbind(se.out, coef(summary(ols.out))[,2]) + } The returned information reflects the combined values and the combined standard error. It appears that there is no way to get the t-statistic, degrees of freedom, or f-values using mi.meld(). Without having to do a manual calculation or use Stata, how can I obtain the degrees of freedom, t-statistic, and f-values? Thanks.
