you're probably just asking it to do too much, such as effectively including to many variables (explicitly or implicitly through dummy variables as cross sections or nominal variables). pair it down to something very simple, get it to work, and then gradually add complications and you'll see more clearly what the problem is.

Hi Class,
Does anyone know what Amelia is trying to tell me with this message:
> a.out <- amelia(imputedata, m = 5, ts = "year", cs = "id", intercs=T) -- Imputation 1 -- 1 2 3 4 5 6 7 8 9 10 11 12 Error in La.svd(x, nu, nv) : error code 1 from Lapack routine 'dgesdd'
Google says that Amelia is not converging, but I'm not sure how to force her! The problem goes away if I remove "intercs=T", but I think the imputations are also much less precise. Any ideas!?

I'm sure I'm not the only one making last minute revisions, so good luck everyone!

Colin
