R help - Jul 2010 - start value in nlminb

Hi, all

I am doing a optimization problem using nlminb. It seems to me that the
result is kind of sensitive to the starting value. (It happened that the
resulting parameter doesn't change from the starting value.) Any suggestions
on giving the starting value ? or any other function that can do
optimization but not being sensitive to the initial guess ?

Thanks for any helps.

Carrie
