Hello,
I am looking for some advice on how to select subsets of variables for
imputing when using the mice package.
>From Van Buuren's original mice paper, I see that selecting variables to be
'skipped' in an imputation can be written as:
ini <- mice(nhanes2, maxit = 0, print = FALSE)
pred <- ini$pred
pred[, "bmi"] <- 0
meth <- ini$meth
meth["bmi"] <- ""
With the last two lines specifying the the "bmi" variable gets skipped over
and not imputed.
And I have come across other examples, but all that I have seen lay out a
method of skipping variables where EVERY variable is named (as "bmi" is
named above). I am wondering if there is a reasonably easy way to select
out approximately 30 variables for imputation from a larger dataset with
around 2500 variables, without having to name all 2450+ other variables.
Thank you,
Ian
