Dear Dr. King,
I'm hoping you can provide some information, or direct me to a resource
for gathering information, regarding the imputation of dichotomous
variables with AMELIA. Specifically, I'm wondering about how
problematic it is to use the "ANOMS" command with the imputation of
dichotomous variables. In statistical consultations, I've been informed
that it should not be a problem to use this command; however, since the
program directs one to use the "AMORDS" command with the imputation of
dichotomous variables, I wanted to gather additional information about
it.
I would be most grateful for any information you can share on this
topic.
Thank you,

Experiments seem to indicate that for imputation, you can use the normal
model underlying Amelia, even though you wouldn't want to use it for the
analysis model. if you choose options appropriately, Amelia will
dichotomize the resulting simulations for convenience of subsequent
analysis. But if that's not necessary for your analysis model, then using
the continuously imputed variable should work fine.

New subject: Commands for Imputing Dichotomous Variables in AMELIA
Here's a pertinent article by Horton et al:
http://www.biostat.harvard.edu/~horton/tasround.pdf
It shows that, when a normal model is used to impute a dichotomous
variable, it's best not to dichotomize the imputed values.
