fitFun

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

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

a numeric value representing the variability in the
 average cell cycle time <code>t</code> (\(h\))

sigma_t

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

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 <code>volEq7</code> at a vector of volume
 (\(\mu m^3\)) values.

models

Implements a methodology for using cell volume
distributions to estimate cell growth rates and division times
that is described in the paper entitled, "Cell Volume
Distributions Reveal Cell Growth Rates and Division Times", by
Michael Halter, John T. Elliott, Joseph B. Hubbard, Alessandro
Tona and Anne L. Plant, which is in press in the Journal of
Theoretical Biology.  In order to reproduce the analysis used
to obtain Table 1 in the paper, execute the command
"example(fitVolDist)".
