Convergence of growth in sample size, n, represented by a subsample of \({\mathfrak {N}}=50\) Monte Carlo replicates (dotted) for the Rotated-Sigmoid population (solid blue) and mean (of the full \({\mathfrak {N}}=500\) replicates) curve (dashed red) for a σ₁=0.10 and b σ₂=0.18. Similar results for the remaining three shapes in Table 1 are in Additional file 1: Figure S.6–S.8
