The Newton's method for finding the root of the equation THETA(t) = 0
can be easily generalized to the case where THETA is monotone, convex,
but not differentiable. Then, the convergence is superlinear. The pur
pose of this note is to show that the convergence is only superlinear.
Indeed, for all alpha is-an-element-of (1, 2), we exhibit an example
where the convergence of the iterates is exactly alpha.
