Abstract
We study the statefinder parameters of a cosmological model based on scale -dependent gravity. The effective Einstein field equations come from an average effective action. From the dynamical system, we derive analytical expressions that improve the con-vergence of the numerical solutions. We determine the statefinder parameters for moderate redshift and compare them with well-known alternatives to ACDM.
