logistic: Logistic growth model

Description

Logistic growth model as defined in Zwietering et al.

Usage

logistic(x, mu, l, z0, zmax)

Arguments

x

numeric vector: time points for which log(OD) must be computed

mu

numeric scalar: maximal growth rate parameter

l

numeric scalar: time lag parameter

z0

numeric scalar: minimal log(OD) parameter

zmax

numeric scalar: maximal log(OD) parameter

Value

numeric vector: log(OD) for the time points given in x
