Query: Implementing multiple imputation for missing data in longitudinal
  studies when models are not feasible: A tutorial on the random hot deck
  approach   Objective: Researchers often use model-based multiple imputation to handle
missing at random data to minimize bias while making the best use of all
available data. However, there are sometimes constraints within the data that
make model-based imputation difficult and may result in implausible values. In
these contexts, we describe how to use random hot deck imputation to allow for
plausible multiple imputation in longitudinal studies.
  Study Design and Setting: We illustrate random hot deck multiple imputation
using The Childhood Health, Activity, and Motor Performance School Study
Denmark (CHAMPS-DK), a prospective cohort study that measured weekly sports
participation for 1700 Danish schoolchildren. We matched records with missing
data to several observed records, generated probabilities for matched records
using observed data, and sampled from these records based on the probability of
each occurring. Because imputed values are generated randomly, multiple
complete datasets can be created and analyzed similar to model-based multiple
imputation.
  Conclusion: Multiple imputation using random hot deck imputation is an
alternative method when model-based approaches are infeasible, specifically
where there are constraints within and between covariates.
