bond.cir: Simulates the values and yields of zero-coupon bonds when the spot rate is modeled by a Feller process.

Description

Simulates the values and yields of zero-coupon bonds when the (annualized ) spot rate (in percent) is modeled by a Feller process satisfying

dr = alpha(beta-r)dt + sigma sqrt(r) dW,

with market price of risk q = q1/sqrt(r) +q2 sqrt(r). The maturities are 1,3,6 and 12 months.

Usage

bond.cir(alpha, beta, sigma, q1, q2, r0, n, maturities, days = 360)

Arguments

alpha

Mean-reversion parameter.

beta

Long term mean.

sigma

Volatility parameter.

q1

Market prime of risk parameter.

q2

Market prime of risk parameter.

r0

Initial rate value.

n

Number of periods.

maturities

Maturities in years (row vector).

days

Days in a year convention (360 default).

Value

P

Bond values.

R

Annual rate for the bond.

tau

Maturities in years.
