“…From now we study the Bayesian global approach to estimate the bandwidth diagonal matrix H = Diag d (h j ) j in (6). Following some authors as Brewer (1998), Zhang et al (2006) and Zougab et al (2013a), we treat the bandwidth matrix H as a random variable with a given prior distribution π (H). The Bayesian inference concerning H conditional on data is made via the posterior density π (H|data) given by π (H|X 1 , X In our study, we assume that each component h j of H = Diag d (h j ) j has a prior distribution denoted π (h j ); e.g., beta and gamma distributions.…”

“…This approach has received an attention in the literature, particularly in the univariate context for symmetric kernels. We can see, Brewer (1998Brewer ( , 2000 who proposed the global and adaptive Bayesian approach. Gangopadhyay and Cheung (2002), Kulasekera and Padgett (2006) and Kuruwita, Kulasekera, and Padgett (2010) proposed a Bayesian local bandwidth selection.…”

“…The adaptive asymmetric kernel estimator of f is given bŷ where K x,h i is the asymmetric associated kernel and h i is the variable bandwidth associated with each observation x i . The main objective is to derive the variable bandwidths h i for Equation (2) by treating h i as a random quantity with a prior distribution π(·).…”

“…The posterior distribution and the Bayes estimators for each variable bandwidth can be derived exactly using the Bayes theorem and both quadratic and entropy loss functions. The Baysian approach with global, local and adaptive versions to bandwidth selection has received considerable attention, see [2,3,8] for univariate symmetric kernel density estimation, [12,13] for univariate kernel density estimation with censored data, [22,23] for discrete associated kernel estimators and [6,7,9,21,24] for multivariate kernel density estimation. These previous studies show that this approach is a very good alternative to classical methods.…”
