st: Test for missingness type
please apologize that my question is not directly related to Stata, but
maybe someone can show me the right way!
I have a dataset with one variable (x) partially missing. I want to
test if the missingness mechanisms is nonignorable (data is MNAR), ie if
P(r=1|x,z) does depend on x, where r is the binary missingness
indicator and z are completely observed covariates.
How can I do this? As I understand, multiple imputation requires the
data to be MAR, so I cannot use -ice- to test for the type of
missingness. Am I right?
Any suggestions are highly appreciated!
