Comparison of stochasticity measurements with and without accounting for quadratic galaxy bias, shown for the full set of Monte Carlo sampled HODs. Plotted are the best fitting values (α₀, α₁) for the stochasticity model of Eq. (2) with linear bias only (open circles) and for the model of Eq. (4), which includes quadratic galaxy bias (solid circles). As in Figs. 6 and A.2, red points correspond to HODs without assembly bias, and blue points correspond to HODs sampled with the assembly bias parameters free.
