Dear R users,
I don't know how to compute an exponential model like this:
proc=a*exp(b*cls), or proc=a*exp(b*cls)+c*exp(d*cls). Please help me to
solve this problem!
Thank you!
My data is:
row.names proc cls
1 0.5 452.616206 0.5
2 1 255.864021 1.0
3 1.5 150.885316 1.5
4 2 86.289600 2.0
5 2.5 56.321559 2.5
6 3 39.504444 3.0
7 3.5 25.570308 3.5
8 4 5.382726 4.0
