Assuming models with log-normal scatter about a median relation of the form $M_\\star \\propto M_\\mathrm{halo}^\\alpha$, the preferred log-slope steepens from $\\alpha \\simeq 1.8$ in the limit of zero scatter to $\\alpha \\simeq 2.6$ in the case of $2$ dex of scatter in $M_\\star$ at fixed halo mass.
