Improved estimation of the covariance matrix under Stein's loss

open access: yes
In this paper, the problem of estimating the covariance matrix of a multivariate normal population is considered. Some new classes of orthogonally invariant minimax estimators which include random mixtures of the modified estimators of proposed by Dey ...

On weighting of bivariate margins in pairwise likelihood

open access: yes
Composite and pairwise likelihood methods have recently been increasingly used. For clustered data with varying cluster sizes, we study asymptotic relative efficiencies for various weighted pairwise likelihoods, with weight being a function of cluster ...

Order restricted inference for sequential k-out-of-n systems

open access: yes
Sequential order statistics have been introduced to model sequential k-out-of-n systems which, as an extension of k-out-of-n systems, allow the failure of some components of the system to influence the remaining ones.
