Hi all:
I'm looking for a package that similar to solver in MS. All I need
is find a
r to satisfy R0=sum( , where t are from 1 to n and Xt are come from
another formula.
The most package I found were to max or min the obj. function. Is
there any
package can do it?
If you minimize , you should get your answer.
Ooops, sorry. Make that:
abs( R0 - sum(r * Xt ) ) # or
( R0 - sum(r * Xt ) )^2

David.
Thanks.
