spr_dl: Spot Rate Function according to the Diebold and Li Version of...

In changshun/termstrc: Zero-coupon Yield Curve Estimation

Description

This function calculates the spot rates for certain maturity dates and a parameter vector according to Diebold/Li (2006).

Usage

spr_dl(beta, m, lambda)

Arguments

beta	a vector of parameters {\bm{β}} = ≤ft(β_0,β_1,β_2\right).
m	one maturity (or a vector of maturities).
lambda	=\frac{1}{τ_1}, a scalar

Details

The spot rate according to Diebold/Li for a maturity m is defined as:

s(m,\bm{β},λ) = β_0 + β_1\frac{1-\exp(-mλ)}{mλ} + β_2≤ft(\frac{1-\exp(-mλ)}{mλ} - \exp(-mλ)\right).

Value

Returns a vector consisting of the calculated spot rates.
