Constraining Cosmological Parameters from Clusterings of
intermediate-redshift Galaxies

We show how the cosmological parameters, including density parameter,
cosmological constant, baryon fraction, bias parameters, etc. can be
estimated from redshift surveys at different redshifts, using maximum
likelihood techniques. We find that the surveys of
intermediate-redshift galaxies, like the Sloan Digital Sky Survey
Luminous Red Galaxies, are quite promising to constrain the
cosmological parameters.
