impl_fwr: Implied Forward Rate Calculation

In termstrc: Zero-coupon Yield Curve Estimation

Description

Calculates the implied forward rates from given spot rates.

Usage

impl_fwr(m, s)

Arguments

m	maturity vector.
s	spot rate vector.

Details

Implied forward rates can be calculated using the following relationship:

f(t',T) = \frac{s(m_T)m_T - s(m_{t'})m_{t'}}{m_T-m_{t'}},

whereas s(m_T), s(m_{t'}) is the spot rate for a maturity m_T,m_{t'} respectively.

Value

The function returns the calculated forward rate vector.

Examples

s <-  spr_ns(c(0.03,0.02,0.01,5),1:30)
impl_fwr(s,m=1:30)
