Hi R-specialists!
I would like to draw some hyperbolic (iso-)lines of a cost function in a
bi-dimensional space ( =shapes of a cost function ), based on (the
general form):
C(x) = c1*Ce + c2*Oe + c3*{ 1 - [ (1 - Ce)^a * (1 - Oe)^b ] }
where:
- Oe/Ce are Omission/Commission (ranging between 0 and 1 ) values in a
bi-dimensional space ( see example of Oe/Ce values [1])
- c1, c2, c3, a and b are some parameters which determine "sensitivity"
of the function
Is there a ready-to-use plotting - function?
Kind regards, Nikos
