Hi, there

I wonder if anyone out there can help me on a problem of using
Splus Nlmin. I am using Nlmin to minimize a non-linear function which has 8
parameters to be estimated.
I'd like to know how to overcome the problem of "singular convergence"
which was given by "conv.type", or to adjust the nlmin options to avoid
this problem.

Thanks a lot
