Fitting (log-transformed least-squares) piecewise log–linear, Weibull, and biexponential models of biphasic decay to population of E. coli over time in Rogers et al.¹⁴ The best fit estimates are a = 0.37, b = 0.072, t* = 9 for the piecewise log–linear model (eq 1), α = 2.1 and β = 0.59 for the Weibull model (eq 3), and a = 0.36, b = 0.069, and c = 0.93 for the biexponential model (eq 5).
