Falling through the cracks: Modeling the formation of social category boundaries
Fig 2
Stable fixed points of boundary positions for both groups: (a) for a uniform attribute distribution, (b) for the symmetrical Beta distribution with shape parameters α = 2 and β = 2, (c) for the asymmetrical Beta distribution with α = 2 and β = 4, and (d) for a bi-modal distribution which is the sum of two Beta distributions, whose shape parameters are α = 2, β = 7, and α = 7, β = 2.
