Real-World Model in the Libor Market Model
Pp. 185-224 (40)
This section of the book develops the theory of simulation in the
LMRW. Although the theory for this is developed similarly to that for the Gaussian
HJM model, the results here are somewhat more complicated than those. In
particular, the drift term in the LMRW has an additional feature that makes it
different from that in the Gaussian model. Moreover, the methods for reducing
dimensionality and constructing the drift term for use in simulation are different
from those for the Gaussian model. Readers are recommended to review the
corresponding results in Chapter 6 to more deeply understand the properties of
Most of the arguments in this chapter are based on Yasuoka (2013a); Section
9.2 is newly written to describe maximum likelihood estimation for the market
price of risk.
Some numerical examples will be shown in Chapter 10, using the same historical
data as in the example for the Gaussian HJM model.
