matlab - Does R support switching between optimizers like STATA does? -
i need implement model show here:
http://www.ssc.upenn.edu/~fdiebold/papers/paper55/drafinal.pdf
the model estimation step on p.315 notes that:
"we maximize likelihood iterating marquart , berndt–hall–hall–hausman algorithms, using numerical derivatives, optimal stepsize, , convergence criterion of 10^-6 change in norm of parameter vector 1 iteration next."
now know stata supports switching between optimizers,
http://www.stata.com/manuals13/rmaximize.pdf
see bottom of p2.
is there r package or matlab function/s can same thing?
specifically need able switch between bhhh , levenberg-marquardt.
kind regards
baz
for r, check out cran task view on optimization. searching page, looks bhhh , marquardt available in separate packages (minpack.lm
, maxlik
, respectively). write own code handle switching between them.
