I imputed six missing values (out of 672) with Amelia. There were five complete columns used to form the imputation model (the IVs), and there were eight DV columns, each with six missing values (an attempt with more DVs failed). I used all default program settings to produce five imputation sets (6 missing data points x 8 variables x 5 sets), which were averaged to get one set of 6x8 imputed values. Is it appropriate to operate on eight variables at once? Are the default program settings appropriate for this example? Thank you.
