Reconstructing equation of state of dark energy with principal component analysis
Zhi-E Liu, Hao-Feng Qin, Jie Zhang +2
We represent a nonparametric method to reconstruct the equation of state for dark energy directly from observational Hubble parameter data. We use principal component analysis (PCA…
