extracting parameters from vector
Dear everybody!
Minimization algorithms usually assume the parameters are in the form of a single
vector. When calculating target function, e.g. log-likelihood, it is much more
pleasant to extract the vector into separate parameters and program the loglik
using them directly. Are ther any more intelligent ways to do that than just
write
sigma <- param[1]
beta <- param[1:1+N]
...
