E estimates obtained analyzing the 16 6-replicate data sets from PGDW using Eqs. 2–4, and their averages (lines). The x-axis numbers represent the data sets, as A1–6, A7–12, …, H7–12, with points for Eqs. 3 and 4 displaced slightly for display purposes. The KaleidaGraph fit results include a priori SEs (Error) [14]. The post-SEs are these values × (χ²/ν)^1/2 = 0.0045, 0.0051, and 0.0047
