Extracting cosmological information from galaxy spectra and observations   of high-redshift objects
  I review the statistical techniques needed to extract information about physical parameters of galaxies from their observed spectra. This is important given the sheer size of the next generation of large galaxy redshift surveys. Going to the opposite extreme I review what we can learn about the nature of the primordial density field from observations of high--redshift objects.
