Factor Analysis of Multidimensional Polytomous Item Response Data Suffering from Ignorable Item Nonresponse.
Bernaards A., Coen; Sijtsma, Klaas
Multivariate Behavioral Research, v34 n3 p277-313 1999
Used simulation to study the problem of missing item responses in tests and questionnaires when factor analysis is used to study the structure of the items. Factor loadings based on the EM algorithm best approximated the loading structure, with imputation of the mean per person across the scores for that person being the best alternative. (SLD)
