Hi there,
I'm trying to conduct nls regression using roughly the below code:
nls1 <- nls(y ~ a*(1-exp(-b*x^c)), start=list(a=a1,b=b1,c=c1))
I checked my start values by plotting the relationship etc. but I kept
getting an error message saying maximum iterations exceeded. I have
tried changing these
