WebDetails. Collinearity diagnostics can be conducted for objects returned from the lm() and glm() function, but also from objects returned from the lmer() and glmer() function from the lme4 package, lme() function from the nlme package, and the glmmTMB() function from the glmmTMB package..

The function computes eigenvalues, condition indices and variance decomposition proportions for each of the regression coefficients in … WebSep 8, 2024 · The definition of multicollinearity is: Given a set of N × 1 predictors X = ( x 1, x 2, ⋯, x m), if x j = ∑ i ≠ j a i x i then we say there is multicollinearity among the predictors. I tend to interpret x j = ∑ i ≠ j a i x i in such a way: The variation along the j t h direction is explained by those directions whose a i is non-zero. pointing work london
