The paper provides the terminology and the description of traditional and current methods and algorithms used in the analysis of incomplete data sets. The methods are assessed in terms of the statistical properties of their estimators. An example is provided for the multiple imputation method. The review indicates that current methods outweigh traditional ones in terms of bias reduction, precision and efficiency of the estimation.}, title={Review of methods for data sets with missing values and practical applications}, type={artykuł}, keywords={missing data pattern, missing data mechanism, complete-case analysis, available-case analysis, single imputation, likelihood-based methods, multiple imputation, weighting methods, wzorzec brakujących danych, mechanizm brakujących danych, usuwanie wierszy, usuwanie wierszy parami, pojedyncza imputacja, metoda największej wiarygodności, imputacja wielokrotna, metody wagowe}, }
