Best-fit power law of the measured real-space 2PCF ξ(r) at 200 h^-1<r < 10⁴h^-1 Mpc. We assume a flat ΛCDM cosmological model, with Ω_Λ = 0.72, Ω_m = 0.28, H₀ = 100 h km s^-1 Mpc^-1, h = 0.7. The real-space 2PCF ξ(r) measured via Eq. (2) for the Greiner, Swift, and SHOALS samples are, respectively, indicated by green circles, red solid triangles, black solid diamonds, and cyan squares with 1σ jackknife error bars that are estimated from (4). The density of random points we use for the estimation is 20 times the density of GRB data. ξ(r) is plotted in equally spaced logarithmic intervals of Δlog ₁₀(r) = 0.2 h^-1 Mpc. The best-fit power laws of the form (5) for the measured ξ(r) are plotted in solid lines, with the best-fit parameters given in the legends.
