is the variance of the random term significant which is statistically significant of variance and covariance? is random intercept significant? is covariance and variance significant why is random chi square test significant in multilevel models does variance and covariance make up the variance? what is the significance of covariance in multilevel modelling is variance significant why is variance significant what is the function of coefficient of variance and covariance variance is significant if not covariance is the coefficient of covariance significant is variance significant and covariance not is covariance significant which term is not significant in the multilevel model for predicting random slopes? what model has covariance as the measure of variance what is the variance of a multilevel model are covariance and variance significant in multilevel models is the variance significant is variance significant in a multilevel multilevel model?
