Hi
I implemented the age-structure model in Gove et al (2002) in R, which is a
nonlinear statistical model. However running the model in R was very slow.
So Dave Fournier suggested to use the AD Model Builder Software package and
helped me implement the model there.
ADMB was incredibly fast in running the model:
While running the model in R took 5-10 minutes, depending on the settings,
in ADMB it took 1-2 seconds!
I'm reporting this so that people who have performance issues with nonlinear
statistical models in R will know that there is a good free alternative for
more difficult problems.
There is also a help platfrom equivalent to the one for R, and people
running it are extremley helpful.
I hope this might help someone
cheers
Beni
