For hot-deck imputation, the fields in an edit-failing record that do not fail edits are matched against edit-passing records. Often the edit-passing record that is closest to the edit-failing record interms of some metric is chosen as the donor record. If the edit-passing records are in random order, then the (possibly erroneous) assumption is that the donation is at random from a valid set of donors. This type of matching is sometimes referred to as statistical matching.
