8.7.3 Proof of Proposition 8.1 in Section 8.5.2Note that Equation 8.143
The numerator in (8.143) is the target distribution, and the denominator is the sampling distribution from which Z t was generated. Hence, for any measurable function h ( ·), we have Equation 8.144
Finally note that both (8.90) and (8.91) are special cases of (8.144). 8.7.4 Proof of Proposition 8.2 in Section 8.5.3In this section we verify the correctness of the residual resampling under a general setting. Let ( ) be a properly weighted sample with respect to p ( x t Y t ) “ without loss of generality, we assume that be the set of samples generated from the residual resampling scheme. The new set consists of copies of the sample for j = 1,..., m , and K r = i.i.d. samples drawn from set with probability proportional to . The weights for the new samples are set to 1. Hence, Equation 8.145
Furthermore, Equation 8.146
Here we assume that Var { h ( x t ) w t } < . Hence, in probability. |
