WitrynaDetails. Impute the missing entries of a data with groups of variables using the iterative MFA algorithm (method="EM") or the regularised iterative MFA algorithm (method="Regularized"). The (regularized) iterative MFA algorithm first consists in coding the categorical variables using the indicator matrix of dummy variables. WitrynaImputing the row mean is mainly used in sociological or psychological research, where data sets often consist of Likert scale items. In research literature, the method is therefore sometimes called person mean or average of the available items. Row mean imputation faces similar statistical problems as the imputation by column means.
