We present a general result giving us families of incomplete and boundedly complete families of discrete distributions. For such families, the classes of unbiased estimators of zero with finite variance and of parametric functions which will have uni

A state-space modeling approach for examining dynamic relationship between multiple brain regions was proposed in Ho, Ombao and Shumway (Ho, M.R., Ombao, H., Shumway, R., 2005. A State-Space Approach to Modelling Brain Dynamics to Appear in Statistic

One way of handling composite hypotheses by SPRT's is to integrate out nuisance parameters under both the null and alternative hypotheses and then form an SPRT. If the prior is improper, Wald inequalities will not hold in general. We provide sufficie

The procedures in traditional discriminant analysis suffer from serious lack of robustness under model misspecifications. Weighted likelihood estimators based on certain minimum divergence criteria have recently been shown (Markatou et al., 1998) to

A geological map is the representation, on a two-dimensional plane, of the disposition of three-dimensional rock bodies exposed on the earth's surface. The problem of mapping is essentially that of dividing an area into “homogeneous” subregions o

A Bayesian approach is considered to study the change point problems. A hypothesis for testing change versus no change is considered using the notion of predictive distributions. Bayes factors are developed for change versus no change in the exponent

We consider arc distance median for circular data. It is shown to admit an almost sure asymptotic linear representation. In the process of deriving this representation, an algorithm to obtain a suitable version of this statistic for a set of observat
We review the relation between P-values and posterior probabilities, and also the Bayesian P-values for composite null hypothesis when there is no alternative.
