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.
