What do we know about cosmography
Abstract In the present paper, we investigate the cosmographic problem using the bias–variance trade-off. We find that both the z-redshift and the $$y=z/(1+z)$$ y = z / ( 1 + z ) -redshift can present a small bias estimation. It means that the cosmography can describe the supernova data more accurat...
