Hello;
I have been trying to run amelia() including the ts and cs arguments.
Amelia accepts the ts argument, but keeps rejecting the cs argument. I keep
getting this error message:
amelia(panel, ts=panel$period, cs=panel$country,
outname="xt")
Amelia Error Code: 6
The 'cs' variable is out of the range of
possible column numbers or is not an integer.
$code
[1] 6
panel = panel data set
country is a number assigned to identify each country (i.e. 1 = Afghanistan,
2=Angola, etc.)
Does anyone have an idea what I am doing wrong?
Thanks
Joe

Check if the panel is balanced and whether there are missing identifiers for
some obs.
table(panel$preriod,panel$country,na.rm=F)

New subject: [gov2001-l] Multiple imputation
We are trying to use Amelia for multiple imputation, but we are running into very basic
problems. The imputed observations fall outside the possible bounds for continuous
variables (e.g. 101 on a scale that has a max of 100). In addition, I have some
categorical variables (with codes 1, 2, 3) and the imputation gives me non-integer
observations.
When I try to use the variables options in step 2 (in Amelia), I run into different sorts
of errors.
How can I get around this problem?
Thanks,
Afamia

Afemia,
Hard to say where the errors come from without seeing the code.
We are trying to use Amelia for multiple imputation,
but we are running

Depending on the precise issue that may be ok (see the Amelia manual for a
discuss of this issue). If you want to avoid this, Amelia also has an option
to declare variables as ordered so that only integer values will be imputed.
