Correcting a statistical artifact in the estimation of the Hubble; constant based on Type Ia Supernovae results in a change in estimate; of 1.2%
Research output: Contribution to journal › Journal article › Research › peer-review
The Hubble constant enters big bang cosmology by quantifying the expansion rate of the universe. Existing statistical
methods used to estimate Hubble’s constant only partially take into account random measurement errors. As
a consequence, estimates of Hubble’s constant are statistically inconsistent and systematically too low. Using the
simplest of the existing methods to illustrate the problem, we show that the change in estimate is 1.2%. The more
advanced techniques suffer from the same deficiency
