Estimating the power-law of the two-point correlation function. An analytical investigation of several estimation procedures.


Abstract (from CDS):

There is empirical evidence that the two-point correlation function of the galaxy point pattern follows for small r reasonably well a power-law expression ξ(r)∝r–γ. This paper analyses the estimation procedure for γ and suggests an estimator for ξ(r) which is well suited for the estimation of γ.
