Hello all!
I have a problem with a double exponential equation.
this are my data's
structure(list(proc = c(1870.52067384719, 766.789388745793,
358.701545859122,
237.113777545511, 43.2726259059654, 148.985133316262, 92.6242882655781,

Dear Catalin,
You can look at ?nls.
Alternatively, you could also consider a linear model as follows, where d
is your data:
# plot your data
with(d, plot(cls, proc, las = 1))
# linear model
fit - lm(proc ~ I(1/cls) + I((1/cls)^2), data = d)
summary(fit)
# plotting
with(d, plot(cls, proc, las

Hello!
I try to compute the double exponential function this code:
f-function(cls,a,b,c,d)a*exp(cls*b)+c*exp(cls*d)
