The Effect of Collapsing Ordered Polytomous Scales on Parameter Estimates in Structural Equation Measurement Models.

Brown, R. L.

Educational and Psychological Measurement, v51 n2 p317-28 Sum 1991

The effect that collapsing ordered polytomous variable scales has on structural equation measurement model parameter estimates was examined. Four parameter estimation procedures were investigated in a Monte Carlo study. Collapsing categories in ordered polytomous variables had little effect when latent projection procedures were used.
