supplying the Hessian to "nlm"
Dear all,
I am trying to minimize a function with 3 parameters using nlm. I have worked out the 2nd derivatives (incl the cross-product terms) and would like to supply them to nlm for evaluation. What I am not sure about is how to set up the Hessian matrix for nlm. That is,
attr(lhat, "hessian") <- c(???)
Do I have to enter all 9 of the entries or just the lower triangle of the matrix? I have not been able to find the documentation in relationship to this. Many thanks for any tips in advance.

error message of: "An object named "mly" cannot be found. I tried other
users that are not in the same owner group of this folder too but nothing
worked.
