SSnegexp: Negative Exponential Model
In BillVenables/WWRCourse: Working with R Course Software and Data

A self-starting model fitting function for a negative exponential model. The model formula is ~ b0 + b1*exp(-t/theta)

1	SSnegexp(t, b0, b1, theta)

`t`	The time variable, or analogue
`b0, b1, theta`	place-holders for the parameter estimates

An evaluated model function, with a derivative matrix attribute

1 2	fm <- nls(Weight ~ SSnegexp(Days, b0, b1, theta), wtloss) coef(fm)
