Hello,

I have recently been toying around with nonlinear fitting for as part of a research job and I've been having problems getting nonlinear fit to:

1) work

2)create a good fit.

Here is my input:

> with(Statistics); with(plots); with(LinearAlgebra);
> list1 := Vector([0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70,
 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130,
 135, 140, 145, 150, 155, 160, 165, 170,...
