The Predictive Accuracy of Full-Rank Variables vs. Various Types of Factor Scores: Implications for Test Validation.

Morris, John D.

Educational and Psychological Measurement, v40 n2 p389-96 Sum 1980

This study compared double cross-validation replication predictive accuracies of six types of factor scores with full-rank data by utilizing data in which classroom achievement was predicted from affective and cognitive variables. Prediction was significantly more accurate for factor scores than for full-rank data. (Author/CP)
