Re: [R] maximum likelihood estimation of 5 parameters

Franco,
You can provide lower and upper bounds on the parameters if you use optim with method="L-BFGS-B".
Hth, Ingmar

Thanks, but when I use L-BFGS-B it tells me that there is an error in optim(start, f, method = method, hessian = TRUE, ...) : L-BFGS-B needs finite values of 'fn'
