Change Scores and Regression Suppressor Conditions.
Glasnapp, Douglas R.
Educational and Psychological Measurement, v44 n4 p851-67 Win 1984
The concept of change is related to suppressor variable conditions in a least square regression model. The domain of conditions necessary for a weighted change score composite to emerge as an underlying construct is mapped and the information loss through arbitrary assignment of weights to a change composite is explored.
