hi,
i have a problem with amelia II on time series like this:
Date Value
1 1988-01-02 2.490
2 1988-02-02 2.400
3 1988-03-01 2.190
4 1988-04-05 1.720
5 1988-05-02 1.860
6 1988-05-26 2.000
if i try this in R:
amelia(m_reihe,m=5,ts=1,cs=2,polytime=3,intercs=TRUE)
i get this error message:
Amelia Error Code: 28
There are too many cross-sections in the data to use an
interaction between polynomial of time and the cross-section.
if i try this in R:
amelia(m_reihe,m=5,ts=1,cs=2,polytime=3)
i get this message from R:
Amelia Error Code: 37
You have a "factor" variable in the data. You may
have wanted to set this as a ID variable to remove it
from the imputation model or as an ordinal or nominal
variable to be imputed. Please set it as either and
try again.
what ist the problem? cant amelia handle this data? what have i to do that it could handle
it?
or do you know an other package for multiple imputation in time series???
best regards falko
