I couldn't get it to estimate the correct values either, so I guess either
your random number generator 'rkappa' is wrong, or your 'Neg.Log.Like'

Hey,
The following is a function I wrote which generates random variables from a
Kappa (2-parameter) distribution.
rkappa <- function(n,beta,alpha){
if(alpha <= 0)
stop("alpha must be greater than zero!")
if(beta <= 0)
stop("beta must be greater than zero!")
Vec <- beta*exp((1/alpha)*(log(
