Hi R-community, I've been trying to fit a model using maximum likelihood in nlm. Upon convergence I examine the hessian and it has a few (not all) positive values on its diagonal, as does its inverse. I am minimizing the negative log likelihood, so I would expect all the members of the diagonal to be negative (I think).
Can anyone shed light on how this might be interpreted? Thanks much, Andrew ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
