Comparison between the full and mean-field models as <i>N</i>₀ and <i>η</i> vary.

The blue (red) dots show the simulated concentration (copy number) distribution for the full model obtained from SSA. The blue (red) squares show the simulated concentration (copy number) distribution for the mean-field model obtained from SSA. The blue (red) curve shows the analytical approximate concentration (copy number) distribution. The model parameters are chosen as N = 50, B = 1, β = 0, κ = 2, α0 = α1 = 1, d = ηf. The growth rate g is determined so that f = 0.1. The parameter ρ and a are chosen so that 〈n〉 = 100 and 〈V〉 = 1. (EPS)
