%description
Perform variable selection in settings with possibly missing data based on
extrinsic (algorithm-specific) and intrinsic (population-level) variable
importance. Uses a Super Learner ensemble to estimate the underlying
prediction functions that give rise to estimates of variable importance.
For more information about the methods, please see Williamson and Huang
(2023+) <arXiv:2202.12989>.
