Poly_fit doesn't really give me what I need. I don't need the
coefficients of a quadratic equation, I want to know the best fit of
the scatter plot to some power of x. I know it's not exactly power
square, but it should be in that neighborhood. Even if I shift all
data to the positive axis, i.e. y = a* (x-x0)^b, any x values less than
x0 is still considered "negative". I don't know what else...maybe I'll
try change of variable or something... thank you for your help.
