I dont understand your question about the hessian. Did you try hessian() function in "numDeriv" on the result from optim directly rather than using "ucminf"? Also, what do you mean by `failed'? What error message did you get?

Hey, R Users my windows is 64 bit windows 7. I am trying to install the package ucminf into my 64 bit version R but cannot. the package I downloaded is from http://cran.r-project.org/web/packages/ucminf/index.html and I installed it with the "install from local zip files", due to I did not connect my computer to internet. did anyone meet this problem and is there a version of ucminf for 64 bit R? the question is: why the ucminf (for 32 bit R) with option hessian=3 always give hessian matrix while most of other methods failed (includiing the option hessian=1 which using numDeriv)? thanks for any information Nan from Montreal ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
