Cosmological Analysis using Panstarrs data: Hubble Constant and
  Direction Dependence
  Hubble tension and the search for preferred direction are two crucial
unresolved issues in modern cosmology. Different measurements of the Hubble
constant provide significantly different values, and this is known as the
Hubble tension. The cosmological principle assumes that the universe is
homogeneous and isotropic; however, deviations from the isotropy have often
been observed.
  We apply the Bayesian tools and the Extreme Value theory dependent statistic
to address the above issues. These techniques have been applied to the
Panstarrs1 type Ia supernovae data. Our analysis for Hubble constant does not
reject the Hubble tension. However, our value is smaller than that of the SHoES
program and agrees with the CCHP value. Extreme value theory-based analysis
indicates that the data does not show direction dependence. As a byproduct of
our technique, we show that the errors in the data are non-Gaussian in nature.
