Hi,

In my study, I want to use the imputed database to perform a generalized method of moments, and I want to know does combining the datasets is a better option since you get more information, or we can simply retain one of the database imputed as Zelig function, which, in my opinion allows a simple linear regression.
 
Thank you so muchfor your kind help

I am having a hard time finding an example on how to combine the
imputed datasets from Amelia in Zelig. As a result, I'm using the 10th
imputed dataset as the one that I use to run my regression models (see
below). Is this ok? Or is combining the datasets a better option since you
get more information? And if so, what is the code to combine the datasets?

outa<-amelia(psub, m=10, noms=noms, ords=ords, idvars=idvars)
write.amelia(obj=outa, file.stem="outdata", extension=NULL, format="csv")
outdata10<-read.table("S:/.../Imp outdata/outdata10", header=T, sep=",",
na.strings="NA", dec=".", strip.white=T)

I appreciate all of the help I can get.
