logistic: Logistic growth model

In cellGrowth: Fitting cell population growth models

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
