Probing the Isotropy in the Sky Distribution of the Gamma-Ray Bursts
  The statistical tests - done by the authors - are surveyed, which verify the
null-hypothesis of the intrinsic randomness in the angular distribution of
gamma-ray bursts collected at BATSE Catalog. The tests use the counts-in-cells
method, an analysis of spherical harmonics, a test based on the two-point
correlation function and a method based on multiscale methods. The tests
suggest that the intermediate subclass of gamma-ray bursts are distributed
anisotropically.
