Single Imputation Techniques of Missing Values: an Experimental Application to Income Data
نویسندگان
چکیده
Riassunto: La mancata risposta parziale è generalmente trattata dagli Istituti Nazionali di Statistica mediante tecniche di imputazione singola. Particolarmente critico è il caso dell’imputazione di variabili di reddito, in termini sia di analisi e modellazione del meccanismo di mancata risposta, sia di preservazione delle proprietà statistiche delle distribuzioni delle variabili oggetto di imputazione. In questo lavoro vengono presentati i primi risultati di uno studio sperimentale condotto in ISTAT al fine di valutare comparativamente l’accuratezza di diverse tecniche di imputazione singola di variabili di reddito.

Background Policy makers need models to be able to detect groups at high risk of HIV infection. Incomplete records and dirty data are frequently seen in national data sets. Presence of missing data challenges the practice of model development. Several studies suggested that performance of imputation methods is acceptable when missing rate is moderate. One of the issues which was of less concern...
متن کاملMultiple Imputation: An Application to Income Nonresponse in the National Survey on Recreation and the Environment
Multiple imputation is used to create values for missing family income data in the National Survey on Recreation and the Environment. We present an overview of the survey and a description of the missingness pattern for family income and other key variables. We create a logistic model for the multiple imputation process and to impute data sets for family income. We compare results between estim...

Background and Objectives: A major challenge that affects the longitudinal studies is the problem of missing data. Missing in the data may result in the loss of part of the information which reduces the accuracy of the estimator and obtain the results will be biased and inaccurate. Therefore, it is necessary to evaluate the missing data mechanism from a longitudinal research and to consider thi...
