Detection significance for a fiducial f(R) gravity model with |fR0| = 10−6, and a fiducial DGP model with Ωrc = 0.0625. The constraints on f(R) gravity from the PDF are stronger than in DGP owing to the additional skewness produced by the scale-dependent fifth force, which is visible in the |fR0| derivatives shown in Fig. 11. Moreover, unlike DGP, where the approximate theory PDF matches the ΛCDM prediction at z = 0, in f(R) gravity the PDF differs from that of the standard cosmology at low redshifts, which allows even more non-linear information to be extracted.
