multiple nls - next fit even after convergence problem
...(residuals(fit.log)^2))
rmse.exp<-sqrt(mean(residuals(fit.exp)^2))
rmse.gomp<-sqrt(mean(residuals(fit.gomp)^2))

I've thought of just storing the 3 model results in a list, and then going through each model object,

help with syntax of nlme function
...n for
nonlinear mixed models. The data frame is called Marouane.chlorophyll. The
model involves a dependent variable (Absorb) and an independent variable
(Ch.surf), which are both numeric variables in the data frame. The data are
hierarchically grouped as Espece, Plante nested within Espece, and Feuille
nested within Plante (i.e. leaves within plants within species). Espece is
defined as a factor and Plante and Feuille are defined as numeric in the
data frame. There are two parameters (k1 and b) and I want to fit a model
in which these two parameters vary randomly across Espece and Plante (with...
