Hi Florian - Zelig 4 fits each of these models separately at the moment, and as a result . If you would like to merge these datasets into a single data table, then the usual practice is with this line: z.out <- zelig(democ ~ loglrgdpch + loglodac + lurban + logpop + lprimsch + llife + lfuelx + alesinae + alesinar + ldemoc + loglrgdpchldemoc + loglodacldemoc + lurbanldemoc + logpopldemoc + lprimschldemoc + llifeldemoc + lfuelxldemoc + alesinaeldemoc + alesinarldemoc, model="probit", data = rbind(outdata1, outdata2, outdata3, outdata4, outdata5, outdata6, outdata7, outdata8, outdata9, outdata10, outdata11, outdata12, outdata13, outdata14, outdata15, outdata16, outdata17, outdata18, outdata19, outdata20, outdata21, outdata22, outdata23, outdata24, outdata25, outdata26, outdata27, outdata28, outdata29, outdata30, outdata31, outdata32, outdata33, outdata34, outdata35, outdata36, outdata37, outdata38, outdata39, outdata40, outdata41, outdata42, outdata43, outdata44, outdata45, outdata46, outdata47, outdata48, outdata49, outdata50)) Note that the call to "mi" has been replaced with "rbind". This will workd if outdata1-50 have similar column structure. A feature request has been opened to support this.

Can Zelig4 can deal with multiple imputation properly now?

However, the old-style is being reimplemented for the next release (late next week on CRAN, early next week as a nightly build). I posted this already, but the issue can be tracked here: https://github.com/IQSS/Zelig/issues/25 On Dec 14, 2012, at 3:59 PM, Olivia Lau wrote: - -- Zelig Mailing List, served by HUIT Send messages: zelig(a)lists.gking.harvard.edu [un]subscribe Options: http://lists.gking.harvard.edu/mailman/listinfo/zelig Zelig program information: http://gking.harvard.edu/zelig/ Zelig mailing list Zelig(a)lists.gking.harvard.edu To unsubscribe from this list or get other information: https://lists.gking.harvard.edu/mailman/listinfo/zelig
