Query: Measuring Galaxy Bias from the High-Order Correlation Functions   In this talk, I will show how to determine the biasing factor $b$ from the
high-order moments of galaxies. The determination is based on the analytical
modeling of primordial peaks and virialized halos and is independent of the
currently unknown density parameter $\Omega_0$ and other cosmological
parameters. The observed high-oder moments of the APM galaxies require that the
biasing factor $b$ be very close to 1, i.e. the optical galaxies are an
unbiased tracer of the underlying mass distribution (on quasilinear scale). The
theoretical argument can be easily generalized to the three-point correlation
function and the bispectrum both of which can used as further observational
tests to the important conclusion of $b\approx 1$ drawn from the high-order
moments. Finally I present our preliminary results of the three-point
correlation functions for the Las Campanas Redshift Survey.
