PHAT0train


The CosmoPhotoz package includes the dataset <code>PHAT0train</code>, containing photometric
data in the astronomical photometric bands u, g, r, i, z, Y, J, H, K, IRAC_1, IRAC_2
and the redshift, for 8478 galaxies. The original PHAT0 dataset, containing 169520 was
split in two (<code><a rd-options="" href="/link/PHAT0train?package=CosmoPhotoz&version=0.1" data-mini-rdoc="CosmoPhotoz::PHAT0train">PHAT0train</a></code> and <code><a rd-options="" href="/link/PHAT0test?package=CosmoPhotoz&version=0.1" data-mini-rdoc="CosmoPhotoz::PHAT0test">PHAT0test</a></code>).


datasets

User-friendly interfaces to perform fast and reliable photometric
redshift estimation. The code makes use of generalized linear models and
can adopt gamma or inverse gaussian families, either from a frequentist or
a Bayesian perspective. The code additionally provides a Shiny application
providing a simple user interface.
