Thanks to the help of people from this forum I was able to bootstrap my data and then apply a model to it. Thanks for all your help. Everything worked out well, but I am having a difficult time getting the new parameter values. I bootstrapped the data 300 times and I want to get the 300 sets of parameter estimates and plot them in Excel. Here is my code: par<-list(Linf=700, K=0.3, to=-0.1) #starting values for parameter estimates vb<-nls(length~Linf*(1-exp(-K*(age-to))), start=par, data=small) #von Bertalanffy growth mode boo<- nlsBoot(vb, niter=300) #This bootstraps my data 300 times and applies the growth model I can get R to plot the 300 parameter estimates if I do the following function: plot(boo) However, I have tried different print function options but have not had any luck getting the 300 parameter estimates. Any advice would be greatly appreciated. Thanks. Mike [[alternative HTML version deleted]]
