In the examples presented thus far the sampling has been unbiased; i.e., the points at which the independent variable was evaluated were selected from the distribution function that directly describes the sampling problem. Although nature always plays unbiased Monte Carlo, the practitioner cannot always do so.

The evaluation of the expectation of a given function of a solution of an SDE with jumps provides via the Feynman-Kac formula, see Sect. 2.7, the solution of a partial integro differential equation. In many applications it is of major interest to obtain numerically these expectations, in particular in multi-dimensional settings.

This chapter develops methods for increasing the efficiency of Monte Carlo simulation by reducing the variance of simulation estimates. These methods draw on two broad strategies for reducing variance: taking advantage of tractable features of a model to adjust or correct simulation outputs, and reducing the variability in simulation inputs. We discuss

In this chapter we shall describe several methods which allow a reduction in the variance of functionals of weak approximations of Ito diffusions. One method changes the underlying probability measure by means of a Girsanov transformation, another uses general principles of Monte-Carlo integration. Unbiased estimators are also constructed.

Variance Reduction for Simulated Diffusions
SIAM Journal on Applied Mathematics, 1994Summary: This article develops some variance reduction techniques for the Monte- Carlo integration of functionals of the solutions of Itô stochastic differential equations (sdes). The Monte-Carlo method for sdes offers a means of calculating solutions to certain types of parabolic partial differential equations and so has applications in various fields

Variance reduction technique plays a crucial role in Monte Carlo methods, as they can significantly reduce the uncertainty inherited in Monte Carlo. While in the previous chapter we already have seen some basic variance reduction methods, here we present more advanced approaches.
