  The main tools in cosmology for comparing theoretical models with the
observations of the galaxy distribution are statistical. We will review the
applications of spatial statistics to the description of the large-scale
structure of the universe. Special topics discussed in this talk will be:
description of the galaxy samples, selection effects and biases, correlation
functions, Fourier analysis, nearest neighbor statistics, Minkowski functionals
and structure statistics. Special attention will be devoted to scaling laws and
the use of the lacunarity measures in the description of the cosmic texture.
