== Arbitrage-Free Nelson-Siegel ==
One approach to affine term structure modeling is to enforce an [[arbitrage-free]] condition on the proposed model. In a series of papers,<ref>{{Cite journal|last1=Christensen|first1=Jens H.

To derive the AFNS model, the authors make several assumptions:
# There are three latent factors corresponding to the ''level'', ''slope'', and ''curvature'' of the [[yield curve]]
