In contrast to the Nelson-Siegel approach, this functional form allows for more than one local extremum along the maturity profile. This can be useful in improving the fit of yield ...
Web2 Nelson-Siegel Term Structure Models Here we review the DNS model and introduce the AFNS class of AF affine term structure models that maintain the Nelson-Siegel factor loading structure. 2.1 The Dynamic Nelson-Siegel Model The original Nelson-Siegel model fits the yield curve with the simple functional form y(τ) = β0 +β1 1−e−λτ λτ ... WebAmong others, Diebold and Li (2006) propose a dynamic model based on the Nelson-Siegel factor interpolation (Nelson and Siegel, 1987), and show that the model not only keeps the parsimony and goodness-of- t of the Nelson-Siegel interpolation, but also forecasts well compared with the traditional statistical models. This dynamic Nelson …
