Estimating cell cycle transition and cell motility parameters, θ = (Rr, Ry, Rg, Mr, My, Mg), with the number of cells in each phase at t = 48 h and cell density data as summary statistics across several synthetic data sets. Synthetic datasets were produced from simulations with true parameter values indicated by dashed vertical lines (note that in (e) the lines overlap). (a,e) Estimated marginal posteriors produced with θ = (0.04, 0.17, 0.08, 4, 4, 4). (b,f) Estimated marginal posteriors produced with θ = (0.04, 0.17, 0.08, 2, 5, 8). (c,g) Estimated marginal posteriors produced with θ = (0.04, 0.17, 0.08, 8, 2, 5). (d,h) Estimated marginal posteriors produced with θ = (0.04, 0.17, 0.08, 5, 8, 2).
