Calcutta Statistical Association Bulletin, Ahead of Print. Rectangular designs are classified as regular, Latin regular, semi-regular, Latin semi-regular and singular designs. Some series of self-dual as well as α–resolvable designs which belong to the…
Calcutta Statistical Association Bulletin, Ahead of Print. We propose a novel nonparametric cluster validity index which can be used to evaluate the unknown number of existing clusters prevailing a data set, to assess the quality of classification for …
Calcutta Statistical Association Bulletin, Volume 74, Issue 2, Page 79-96, November 2022. We study the problem of misspecification when the model proposed by the statistician (theoretical model) has a cusp-type singularity in the drift but the real mod…
Calcutta Statistical Association Bulletin, Ahead of Print. In this article, some new characterization results based on residual and past lifetime Renyi’s entropy in the context of reliability modelling are examined. Relative residual entropy is propose…

Calcutta Statistical Association Bulletin, Ahead of Print. The stochastic comparisons of parallel and series systems are worthy of study. In this article, we present some stochastic comparisons of parallel and series systems having independent componen…
Calcutta Statistical Association Bulletin, Ahead of Print. An alternative and simple method of construction of balanced array, orthogonal and proportional frequency main effect plans and asymmetrical non-orthogonal main effect plans using incidence mat…
Calcutta Statistical Association Bulletin, Volume 74, Issue 1, Page 27-41, May 2022. Storey’s bootstrap estimator for the proportion of true null hypotheses (π0) has a known bias structure but the amount of bias is obviously unknown. A new method has b…
Calcutta Statistical Association Bulletin, Volume 74, Issue 1, Page 62-72, May 2022. In this article, we study a periodic review inventory model for non-instantaneous deteriorating items when the length of a reorder cycle is known and the rate of deter…
Calcutta Statistical Association Bulletin, Volume 74, Issue 1, Page 7-26, May 2022. Here we propose a zero-truncated version of the alternative hyper-Poisson distribution of Kumar and Nair[] and study some of its statistical properties. We derive some …
