fitFun {cellVolumeDist}

Model for the distribution of cell volumes

Description

This is an implementation of a model for the distribution of cell volumes that constitutes Equation 7 in the paper listed in the references. It evaluates volEq7 at a vector of volume (\mu m^3) values.

Usage

fitFun(par,  t = 29, sigma_t = .3*t, V = 1:100)

Arguments

par

a list of parameter starting values, with elements A, r (\mu m^3/h), and sigma_r (\mu m^3/h)

t

a numeric value representing the average cell cycle time (h)

sigma_t

a numeric value representing the variability in the average cell cycle time t (h)

V

a numeric value representing the (vector of) volumes (\mu m^3) at which the model is to be evaluated

Value

A numeric vector representing a cell volume (\mu m^3) distribution.
