Hi All,
I am trying to do some D o E. I would like to find the optima
(maxima) of a 2 dimensional lm with quadratic terms.
I'm sure there is a really simple solution but i can't find it.
Also would there be any way to find some sort of confidence limits on these
optima?
Any help most appreciated!
Cheers,
Ben
