Hi.
I am trying to figure out two issues on Amelia II:
1) How to determine the q-order polynomials: The software allows one to specify
between 0-3. Since I am mostly interested in cross-section shifts, setting it
to 0 is not an option. But how would I determine to which order I'd set them
to? Also: in the Honacker and King (2006) article on missing values LOESS or
spline basis functions are recommended. Does Amelia II offer insights about
these two techniques as well?
2) How to set the case prior efficiently: I have 135 developing countries in my
data and would like to use a case prior to identify existing
similarities/differences between countries. Theoretically it makes sense to
group the countries by region/sub-region in terms of their similarity. Is it
possible to identify countries' similarities by regions/sub-regions rather than
making pairwise assessments? Also: the above-mentioned Honacker and King (2006)
article talks about observational priors but does not discuss the
advantages/drawbacks of case priors. Could you help me out here?
I look forward to your response.
Thanks very much!
