nonlinear least square
Hi to all,
Is there a way we can fit a non linear model to a data using non linear
least square method without necessarily initialising the parameters of the
model. I find it hard to get the initial value of the parameter. Below is a
sample of the code I have.
*nachman<-nls(OARmedium$OCCUPANCY~1exp(-alpha*OARmedium$MEAN^beta),start=list(alpha=0.2,beta=0.1),data=OARmedium)summary(nachman)*

...ect. And it will usually take more time and computing
effort because it tries hard to reduce the SS.
A reproducible example would get you a more informed response.
