Detailed Description

series (a local approximation).

The TaylorApproximation class provides a local approximation based on data from a single point in parameter space. It uses a first- or second-order Taylor series expansion: f(x) = f(x_c) + grad(x_c)' (x - x_c) + (x - x_c)' Hess(x_c) (x - x_c) / 2.
