The counts-in-cells and the two-point angular correlation function method are used to test the randomness in the angular distributions of both the all gamma-ray bursts collected in the BATSE Catalog, and also their three subclasses (“short,” “intermediate,” “long”). The methods eliminate the non-zero sky-exposure function of BATSE instrument. Both tests suggest intrinsic non-randomness for the intermediate subclass; for the remaining three cases we use only the correlation function method. The…

TLDR
This book provides an introduction to statistical methods for analysing data in the form of spatial point distributions, described in intuitive terms and illustrated by many applications to real data drawn from the biological and biomedical sciences.
