Subject: IMPUTE: interaction question
Message-ID: <[email protected]>
Does anyone know whether interaction terms (for categorical variables)
should be included in the multiple imputation process, versus just being
created after the dataset has been imputed? I have been taking the latter
approach out of concern about potential internal inconsistencies in the data
(e.g. separately imputed interaction term is imputed as a "1" when one of
the individual effect terms is imputed as a "0" for the same observation).
Any insight is appreciated. Thanks.
