WebMay 20, 2024 · The approach taken is based on the method of Rao-Blackwellization which enhances the accuracy of unbiased estimates available from the first interim analysis by taking their conditional expectations given final sufficient statistics. Analytic approaches to determine such expectations are difficult and specific to the details of the design ...

WebRao-Blackwellization (Casella & Robert,1996). Rao-Blackwellization has been used in previous work to reduce the variance of stochastic gradients (Ranganath et al.,2014; Titsias K & Lazaro-Gredilla´ ,2015), but in a setting orthog-onal to ours, one with multivariate discrete random vari-ables. Our focus here is on a univariate discrete random http://www.statslab.cam.ac.uk/~rrw1/stats/S03.pdf WebRao{Blackwellization in the MCMC era Christian P. Robert 1;2 3 and Gareth O.
