Due to the ease in linearizing the model, a grid search or an OLS approach using a fixed shape parameter are popular estimation procedures. Charles R. Nelson Andrew F. Siegel University of Washington Parsimonious Modeling of Yield Curves* I. Introduction The need for a parsimonious model of the yield One of the common parametric models which has found the interest of users is the Nelson-Siegel model. This was first proposed by Charles Nelson and Andrew Siegel of the University of Washington in 1987.

Indeed the two models are just slightly dif- The Nelson-Siegel's model to describe the yield curve is: $$y_t (\tau) = \beta_ {0t} + \beta_ {1t} \frac {1-\exp (-\lambda \tau)} {\lambda \tau} + \beta_ {2t} \left (\frac {1-\exp (-\lambda \tau)} {\lambda \tau} - \exp (-\lambda \tau) \right)$$ The Nelson-Siegel model can generate a variety of yield curve shapes including upward sloping, downward sloping, humped, and inversely humped, but it can not generate yield curves with two or more local minima/maxima that are sometimes (though rarely) observed in the data. Diebold and Li (2003) reformulated the original Nelson-Siegel expression as The Nelson-Siegel- [Svensson] Model is a common approach to fit a yield curve. Its popularity might be explained with economic interpretability of its parameters but most likely it is because the European Central Bank uses it. The Nelson-Siegel-Svensson model (NSS) is one of the models that is most frequently used by central banks to estimate the term structure of interest rates.

In comparison, our volatility components approach has better economic interpretations.1 The rest of the article is structured as follows. Section 1 develops the Nelson–Siegel model in the option implied volatility context. 2019-11-13 particular, if the Nelson-Siegel model is suﬃciently ﬂexible and if it is applied to data that is generated in a competitive trading environment, it is likely that most of the yield curves generated by the model fulﬁll the no-arbitrage constraints.
