I have a dataset with a variable v1 with some missing data. I would like to impute 10 datasets and then generate restricted cubic splines variables for v1 to then use them in a model on the imputed datasets. Example code below. Many thanks in advance.
Code:
set seed 123 mi set wide mi register imputed v1 v2 local var_list outcome v3 v4 v5 mi impute chained (regress) v1 (ologit) v2 = `var_list', add(5) *I would like to generate the splines here, using rcsgen, but don't seem to be able to generate them in a way that stata recognises them in the next line mi estimate, or: logistic outcome v1_rcs v2 v3 v4 v5
