... are the basis of Bayesian inference. The results also hold for Bayesian inference provided the parameters are distinct, i.e., their prior distributions are independent. For ... and R is The likelihood ignoring the missing-data process, or marginal density of y obs in the absence of selection, is obtained by integrating out the mis...

Furthermore, since the estimation quality of the first stage is available, we use BLUE to obtain ˆ θ for exploiting the quality information instead of using the MLE in the ... levels. It is interesting to see that using more training symbols does not improve the performance of the MLE as expected, because inserting training symbols will reduce th...
