Summarizing the goodness of fit of generalized linear models for longitudinal data

Stat Med. 2000 May 30;19(10):1265-75. doi: 10.1002/(sici)1097-0258(20000530)19:10<1265::aid-sim486>;2-u.


This paper extends four goodness-of-fit measures of a generalized linear model (GLM) to random effects and marginal models for longitudinal data. The four measures are the proportional reduction in entropy measure, the proportional reduction in deviance measure, the concordance correlation coefficient and the concordance index. The extended measures satisfy the basic requirements for measures of association. Two examples illustrate their use in model selection.
