We develop a new method to estimate galaxy physical parameters, such as stellar masses, or star formation histories. This method is based on principal component analysis (PCA), using the information in rest-frame 3700-5500Å spectral region. The derived physical parameters are then applied to study the evolution of the most massive galaxies from z ~ 0.6 to the local Universe, especially on how radio AGN influence the recent star formation histories of host galaxies.
