Detailed Description

Nelson-Siegel fitting method.

Fits a discount function to the form $ d(t) = \xp^{-r t}, $ where the zero rate $r$ is defined as [ r \quiv c_0 + (c_0 + c_1)*(1 - exp^{-ppa*t}/(ppa t) - c_2 exp^{ - ppa t}. ] See: Nelson, C. and A. Siegel (1985): 'Parsimonious modeling of yield curves for US Treasury bills.' NBER Working Paper Series, no 1594.
