Confronti tra misure di accuratezza per la stima di mancate risposte in indagini longitudinali

R. Gismondi
In this paper, dealing with the problem of estimating missing values concerning a certain Y variable, we have first tried to define 8 different estimators, derived from a general imputation model. Then 7 different accuracy measures (or quality indicators of the imputation process) have been proposed and commented. Finally, starting from a concrete and strongly skewed population an ignorable non response mechanism has been simulated, in order to compare estimators and quality indicators. Results showed...
