Re-considering the variance parameterization in multiple precision models
variance parameterization multiple precision models
2009/9/22
The simplex parameterization has at least two attractive features.
First, it typically leads to simple MCMC algorithms with good mixing proper-
ties regardless of the parameterization used to specif...
Upper bounds for the expected Jefferson rounding under mean-variance-skewness conditions
Gain of rounding JeEerson rounding geometric moment theory four-dimensional geometry
2009/9/22
For the class of nonnegative random variables with
given mean, variance, and skewness and support bound, we present
a sharp upper bound for the expectation of rounding due to the Jefferson
rule. Th...
A Default Conjugate Prior for Variance Components in Generalized Linear Mixed Models(Comment on Article by Browne and Draper)
Choice of prior hierarchical models noninformative priors random effects
2009/9/21
For a scalar random-eect variance, Browne and Draper (2005) have found that the uniform prior works well. It would be valuable to know more about the vector case, in which a second-stage prior on the ...
Prior distributions for variance parameters in hierarchical models(Comment on Article by Browne and Draper)
Bayesian inference conditional conjugacy folded-noncentral-t distribution hierarchical model multilevel mode weakly informative prior distribution
2009/9/21
Various noninformative prior distributions have been suggested for
scale parameters in hierarchical models. We construct a new folded-noncentral-t
family of conditionally conjugate priors for hierar...

Simultaneous estimation of the mean and the variance in heteroscedastic Gaussian regression
Gaussian regression heteroscedasticity model selection Kullback risk convergence rate
2009/9/16
Let $Y$ be a Gaussian vector of $R^{n}$ of mean $s$ and diagonal covariance matrix $Gamma$. Our aim is to estimate both $s$ and the entries $sigma_{i}=Gamma_{i,i}$, for $i=1,dots,n$, on the basis of t...

2009/4/22
We consider a zero sum stochastic differential game which involves two players, emph{the controller} and emph{the stopper}. The stopper selects the stopping rule which halts the game. The controller c...
Strong Approximation for Mixing Sequences with Infinite Variance

2009/4/22
In this paper we prove a strong approximation result for a mixing sequence with infinite variance and logarithmic decay rate of the mixing coefficient. The result is proved under the assumption that t...
