An Empirical Assessment of the Performance of Variance Components Tests under Contaminated Error Distributions with Application to Random-Intercept Regression Models

Testing zero variance components is a common practice under random-intercept models. Various test exist to check the need for random effects in such models. Although many of those tests have correct Type-I error rate even when the error components are not normally distributed, an empirical assessmen...
