Hi all,
I want to optimize a function fn using optim. This function fn calls
the .C function in it with a function name and arguments given to fn,
i.e. something like this pseudocode:
fn - function(par, some params for fn) {... .C(Cfunction, ...) ...}
optim(par, fn, some params for fn)
In my
Hi,
I have to draw samples from an asymmetric-Laplace-Normal distribution:
f(u|y, x, beta, phi, sigma, tau) \propto exp( - sum( ( abs(lo) +
(2*tau-1)*lo )/(2*sigma) ) - 0.5/phi*u^2), where lo = (y - x*beta) and
y=(y_1, ..., y_n), x=(x_1, ..., x_n)
