volEq7 {cellVolumeDist}

Model for the distribution of cell volumes

Description

This is an implementation of a model for the distribution of cell volumes (um^3) that constitutes Equation 7 in the paper listed in the references.

Usage

volEq7(A = 1, r = 1, sigma_r = 1,  t = 29, sigma_t = .3*t, V = 1)

Arguments

A

a numeric value that represents the starting value for a linear scaling parameter associated with the volume distribution curve

r

a numeric value that represents the starting value for the rate of cell growth parameter (h)

sigma_r

a numeric value that represents the starting value for the variability in the rate of cell growth parameter r (um^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 volume (um^3) at which the model is to be evaluated

Value

A numeric value representing the frequency of cells expected having volume V (um^3).
