A three-node spline reconstruction of holographic dark energy improves chi-squared over LambdaCDM by about 10 to 12, but Bayesian evidence gives no clear preference.

abstract
The idea of relating the infrared and ultraviolet cutoffs is applied to Brans-Dicke theory of gravitation. We find that extended holographic dark energy from the Hubble scale or the particle horizon as the infrared cutoff will not give accelerating expansion. The dynamical cosmological constant with the event horizon as the infrared cutoff is a viable dark energy model.

How Holographic is the Dark Energy? A Spline Nodal reconstruction approach
A three-node spline reconstruction of holographic dark energy improves chi-squared over LambdaCDM by about 10 to 12, but Bayesian evidence gives no clear preference.
