Hi Gary--
I recently started using Amelia (Windows version) to generate
multiply-imputed datasets and Clarify package / -miest- to run statistical
models and pull the parameter estimates together. I am still learning how to
use it.
I have a couple of question:
1) Is it possible to set a seed number, both in Amelia and in Clarify, so
results can be exactly reproduced?
2) Is it possible to have Amelia save the settings of any run in a file, to
document these settings?
3) (Just a wish list item. I don't think this is possible). Is it possible
to run Amelia from a batch file, something similar to Stata's -do- files? It
would save so much typing...
4) (Another item to add to the wish list). Do you have any plans to have an
Amelia version for Stata? Or is it just unpractical? (I would then have
access to all the parts of Amelia which currently only work with the Gauss
version, such as the use of other MI algorithms, and the use of graphs.)
Thank you for your help,
--Estie Hudes.

in Amelia, you can do this in Amelia for Gauss. rndseed and a number will
do it.
2) Is it possible to have Amelia save the settings of any run in a file, to

they're all stored in the data buffer.
3) (Just a wish list item. I don't think this is possible). Is it possible

You can do this too, but only in Amelia-for-Gauss.

well, clarify will use the output from Amelia, but you need to run Amelia
separately. The stata command language would make creating a version of
Amelia entirely within stata extraordinarily difficult and slow. Although
I bet someone could come up with a way of running Amelia via a batch line
called from a wrapper within stata. You'd have to talk to the Stata folks
about that...

you can set a seed for Clarify as well. Before running estsimp, type "set
seed 12345" or whatever value you'd like for the seed.
