A Simulation Study of the Difference Chi-Square Statistic for Comparing Latent Class Models under Violation of Regularity Conditions.

Holt, Judith A.; Macready, George B.

Applied Psychological Measurement, v13 n3 p221-31 Sep 1989

The robustness of the likelihood ratio difference statistic to the violation of a regularity condition when used to assess differences in fit provided by pairs of latent class models was investigated. Recommendations are made regarding the use of the statistic under violation of the regularity condition. (SLD)
