fitFun: 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.
