SSgompertz2: Self-starting Model Functions
In BillVenables/WWRCourse: Working with R Course Software and Data

Self-starting model fitting functions for non-linear Gompertz Growth Curve models. The non-linear model is of the form ~ exp(b0 - b1*rho^x)

SSgompertz2(x, b0, b1, rho)

SSgompertz3(x, b0, b1, rho)

`x`	numeric vector, time variable or analogue
`b0, b1.rho`	place-holders for the parameter estimates.

The functions are not used directly, but in non-linear model formulae

An evaluated model function, with a derivative matrix attribute
