14) Consider a homogeneous Markov chain with the following transition pdf: f (x|y) = b 1 . ???? 1 + b2 (x − ????y)2 Show that it is irreducible. 145) if ???? ≠ 0. 15) Consider a homogeneous Markov chain with the following transition pdf: ⎧ 2x ⎪y, f (x|y) = ⎨ 2(1−x) ⎪ 1−y , ⎩ x ∈ (0, y), x ∈ (y, 1) if y ∈ (0, 1) and f (x|y) = 0 otherwise. Show that is irreducible, and ﬁnd its stationary distribution. 31 2 Monte Carlo Integration In this chapter, we review the basic algorithms for the calculation of integrals using random variables and deﬁne the general strategy based on the replacement of an integral by a sample mean.
11) over points randomly distributed in the same interval. 15) where, again, there are no restrictions about the function G(x), but we demand that f????̂ (x) has the required properties of a probability density function: that is, nonnegative and normalized. The key point is to understand the integral as the average value of the function G(x) with respect to a random variable ????̂ whose probability density function is f????̂ (x): I = E[G]. 12). 13). 13), but using for xi , i = 1, … , M values of the random variable ????̂ whose pdf is f????̂ (x).
It is straightforward to write a computer program to implement this algorithm. d0 do i=1,M g0=g(ran_f()) r=r+g0 s=s+g0*g0 enddo r=r/M s=sqrt((s/M-r*r)/M) end subroutine mc3 The main difference with respect to the uniform sampling is the substitution of the values of the uniform distribution (b-a)ran_u()+a distributed according to a uniform distribution in (a, b) by the values ran_f() distributed according to the distribution f????̂ (x). And how do we implement this function? Although we will devote next chapter entirely to this question, let us give now some basic results.
