Re: [R] A question about optim function in R

For this and the nlminb posting, a reproducible example would be useful. The optimx package (I am maintainer) would make your life easier in that it wraps nlminb and optim() and other solvers, so you can use a consistent call. Also you can compare several methods with opm(), but do NOT use this fo

[R] A question about nlminb function

Hi, I use the function nlminb to maximize a function and got convergence with the message false-convergence. I know the reason may be the gradient $B"`(Bf(x) may be computed incorrectly, the other stopping tolerances may be too tight, or either f or $B"`(Bf may be discontinuous near the cur

[R] A question about optim function in R

Hi, I encounter a problem in R. My program is as follows. lower <- c(-Inf,-Inf,-Inf,-Inf,0,0,0,-1,-1,-1) upper <- c(Inf,Inf,Inf,Inf,Inf,Inf,Inf,1,1,1) out <- optim(parm,logLik,method='L-BFGS-B',lower=lower,upper=upper,hessian=hessian) As you can see, I have restricted parameter[5], parameter[6]
