According to Allison(2002) you cannot do this. Not only will the point
estimate for the variable with missing values be biased, but also the
point estimates for other variables, even if the data were MCAR
(Allison 2002: 9-10), in which case listwise deletion may be an
acceptable alternative to imputation.
