Posted: Tue Apr 23, 2024 8:59 am
bondspline.rpf does a cubic spline approximation to the discount function, as described in McCulloch(1971), "Measuring the Term Structure of Interest Rates", Journal of Business, vol 44, pp 19-31. The cubic spline with a fixed set of knot points can be estimated as a linear regression on a generated set of regressors with a base set making up a cubic polynomial, along with one term per knot for the cube of the excess above it.
