which random elements in aic is aic conditional does the off diagonal elements of random effects matrix count for a full degree of freedom how many offdiagonal elements are used for aIC? what counts as degree of freedom in aic? which statement is true for an aic? aic definition and example which aic is used in a nonlinear mixed effects model? what is the diagonal of the random effect matrix? what does the diagonal count in the aic arithmetic does ac count as a degree of freedom what are diagonal elements of ac is random effects matrix conditional what is aic for mixed effects how do you determine aic what is the aic used for in a multivariate model? what is the definition of aic does diagonal count as degrees of freedom do diagonal elements really count towards degrees of freedom? how would the off diagonal elements of the random effect matrix contribute to the degree of freedom
