In questo lavoro si studia il problema della discrepanza fra la distribuzione generatrice dei dati imputati e quella che genera i dati veri, non osservati (matching noise). In particolare, si confrontano diverse tecniche di imputazione non parametrica, sia dal punto di vista teorico, sia mediante un’esperimento di simulazione.
Imputation, matching noise, kNN method, hot deck.
