Abstract
In this paper, we consider two modified Chevallier–Polarski–Linder (CPL) models in the background of homogeneous and isotropic FLRW space-time model. From the observational dataset (Pantheon + BAO + HST) we find that the logarithmic form of the equation of state for the dark energy (model II) is more preferred with the use of AIC and BIC and tightly constrained than the other form of the equation of state parameter (model I). However, model I is more favored compared to the model II in the context of Bayesian evidence. Finally, for [Formula: see text] tension it is found that model I is more preferable than model II.
