Re: [amelia] Amelia Digest, Vol 152, Issue 1

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 Mouna kessentiniPh, D StudentUniversity of Tunisia& University Paris 8  Le Samedi 3 janvier 2015 18h00, &quot;amelia-request(a)lists.gking.harvard.edu&quot; &lt;amelia-request(a)lists.gking.harvard.edu&gt; a écrit : Send Amelia mailing list submissions to     amelia(a)lists.gking.harvard.edu To subscribe or unsubscribe via the World Wide Web, visit     https://lists.gking.harvard.edu/mailman/listinfo/amelia or, via email, send a message with subject or body 'help' to     amelia-request(a)lists.gking.harvard.edu You can reach the person managing the list at     amelia-owner(a)lists.gking.harvard.edu When replying, please edit your Subject line so it is more specific than "Re: Contents of Amelia digest..."

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.
