For my master thesis I have fitted an individual tree diameter growth model
and a survival probability model separately using R, but I was told that
simultaneous estimation of these two models would minimize overall errors
and provide a variance-covariance matrix as a whole.
In that respect, can you please tell me if I can do it with nlssystemfit
using SUR (seemingly unrelated regression) method? If not, do you know how
can I do it in R?
My equations are:
- tree diameter growth model
- survival probability model
