Arbitrage-free Nelson Siegel model with R code
Sang-Heon Lee This article explains how to estimate parameters of the Arbitrage-Free dynamic Nelson-Siegel (AFNS) model (Christensen, Diebold, and Rudebusch; 2009, Christensen, Diebold, and Rudebusch; 2011) using Kalman filter. We estimate not only parameters but also filtered latent factor estimates such as level, slope, and curvature using R code. 1. AFNS modelAFNS model ...
