Evaluation of a New Approach for Edit and Imputation of Social and Demographical Data with Hierarchical Structure

چکیده
Riassunto: In questo lavoro viene proposto un nuovo approccio, suggerito dalla Teoria dei Grafi, per ridurre, nel processo di correzione, la perdita di informazioni derivante da cancellazioni improprie dei dati, e per migliorare la qualità dell’imputazione, nel caso in cui vengano effettuati diversi passi di correzione per imputare dati con struttura gerarchica. Il nuovo approccio è stato confrontato con un approccio tradizionale usando i dati del Censimento della Popolazione del 1991; i risultati ottenuti hanno evidenziato un miglioramento consistente della qualità del processo di correzione. La metodologia proposta sarà, quindi, utilizzata per la correzione di alcune variabili rilevate con il Censimento della Popolazione del 2001.

Accuracy evaluation of different statistical and geostatistical censored data imputation approaches (Case study: Sari Gunay gold deposit)
Most of the geochemical datasets include missing data with different portions and this may cause a significant problem in geostatistical modeling or multivariate analysis of the data. Therefore, it is common to impute the missing data in most of geochemical studies. In this study, three approaches called half detection (HD), multiple imputation (MI), and the cosimulation based on Markov model 2...
متن کاملAn Empirical Comparison of Performance of the Unified Approach to Linearization of Variance Estimation after Imputation with Some Other Methods
Imputation is one of the most common methods to reduce item non_response effects. Imputation results in a complete data set, and then it is possible to use naϊve estimators. After using most of common imputation methods, mean and total (imputation estimators) are still unbiased. However their variances (imputation variances) are underestimated by naϊve variance estimators. Sampling mechanism an...

Selecting the most suitable alternative under uncertainty is considered as a critical decision-making problem that affects the success of organizations. In the selection process, there are a number of assessment criteria, considered by a group of decision makers, which often could be established in a multi-level hierarchy structure. The aim of this paper is to introduce a new hierarchical multi...
