- Abstract
- The Dynamic Nelson-Siegel is a popular model for forecasting interest rates. However, the DNS has many variations and estimation procedures, it is not always clear which one is the most appropriate. Following an empirical out-of-sample approach, we first analyse various criteria for fixing the shape parameter in the context of the two-step estimation method of the DNS. We then compare the two-step and one-step approaches on market and simulated data. Lastly, we perform a robustness assessment of the two-step and one-step independent-factor DNS forecasting performance with respect to key parameters and starting values.
