fwr_sv: Forward Rate Calculation according to Svensson (1994).

Description

Calculate forward rates according to Svensson (1994).

Usage

fwr_sv(beta, m)

Arguments

beta

parameter vector ${\bm{\beta}} = \left(\beta_0,\beta_1,\beta_2,\tau_1,\beta_3,\tau_2\right)$.

m

maturity or vector of maturities.

Value

• Returns the a vector with the calculated forward rate (vector).

Details

The forward rate for a maturity $m$ is calculated according to the following formula:

$$f(m,\bm{\beta}) = \beta_0+\beta_1\exp\left(-\frac{m}{\tau_1}\right)+\beta_2\left[\left(\frac{m}{\tau_1}\right)\exp\left(-\frac{m}{\tau_1}\right)\right] +\beta_3\left[\left(\frac{m}{\tau_2}\right)\exp\left(-\frac{m}{\tau_2}\right)\right].$$
