Multinomial Data By KWANG WOO AHN and KUNG-SIK CHAN Department of Statistics and Actuarial Science, The University of Iowa, Iowa City, IA USA [email protected] [email protected] Summary We propose a new, block Gibbs sampling scheme for incomplete multinomial data. The new approach facilitates maximal blocking, thereby reducing serial dependency and speeding up the convergence of the ...
This paper gives precise, easy to compute bounds on the convergence time of the Gibbs sampler used in Bayesian image reconstruction. For sampling from the Gibbs distribution both with and without the presence of an external eld, bounds that are N 2 in the number of pixels are obtained, with a proportionality constant that is easy to calculate.
Background and Objectives: Analysis of ordinal data outcomes could lead to bias estimates and large variance in sparse one. The objective of this study is to compare parameter estimates of an ordinal regression model under maximum likelihood and Bayesian framework with generalized Gibbs sampling. The models were used to analyze ovarian hyperstimulation syndrome data. Methods: This study use...
