Implication

Simulation study evaluates variance partition coefficient definitions in multi-level logistic regression, highlighting the impact of estimation methods on variance attribution.

Key Points

To derive explicit variance partition coefficient formulas for multi-level logistic regression models and assess their statistical and distributional behavior.
Derived formulas extending four variance partition coefficient (VPC) definitions to multi-level logistic regression contexts.
Evaluated distributional properties and bivariate dependence across levels using simulations alongside an empirical vegetation dataset.
Compared variance partitioning outcomes generated via Laplace approximation versus penalized quasi-likelihood estimation techniques.
Demonstrated systematic associations and bivariate dependencies among VPC values derived at different hierarchical levels.
Identified substantial estimation discrepancies between the Laplace approximation and penalized quasi-likelihood methods.
