Description Usage Arguments Value References Examples
This function imputes for all missing responses using two-way imputation. Integrated responses are obtained by rounding imputed values to the closest possible response value. If a case showed missingness on all the variables (i.e., empty record), the missing values are replaced by item means first. see Sijtsma and van der Ark (2003) <doi: 10.1207/s15327906mbr3804_4>;
