Calcutta Statistical Association Bulletin, Ahead of Print. A new three-sample nonparametric estimation of ordered survival functions is proposed based on three independent samples from distribution functionsF(x),G(x) andH(x), which satisfy the stochast…
Calcutta Statistical Association Bulletin, Ahead of Print. This article proposes two estimators for two semiparametric count regression models, namely semiparametric partially Poisson (SPPO) and semiparametric partially zero-inflated Poisson (SPZIP), v…
Calcutta Statistical Association Bulletin, Ahead of Print. The Laplace distribution is popular in the fields of economics and finance; however, empirical data often exhibit asymmetry and boundedness on one side of the support, features that the Laplace…
Calcutta Statistical Association Bulletin, Ahead of Print. Panel count data arise when recurrent events experienced by the study subjects are recorded only at discrete observation times. In this article, we focus on the regression analysis of panel cou…
Calcutta Statistical Association Bulletin, Ahead of Print. This article considers a classical optimal design problem of finding saturated D-optimal designs for the quartic polynomial model for mixture experiments. The necessary and sufficient condition…
Calcutta Statistical Association Bulletin, Ahead of Print. In this article, we have proposed a difference-cum-exponential type estimator for estimating population mean by using information on two auxiliary variables under non-response, in which the exp…
Calcutta Statistical Association Bulletin, Volume 77, Issue 2, Page 225-243, November 2025. Estimating the output gap and potential output presents a perpetual challenge for policymakers. Model-based estimations can yield inconsistent results if the un…
Calcutta Statistical Association Bulletin, Ahead of Print. A two-armed ‘single-dose treatment’ response adaptive randomization (RAR) design is developed for ordinal categorical responses using stochastic superiority measure.[1–3]Doubly adaptive biased …
Calcutta Statistical Association Bulletin, Volume 77, Issue 2, Page 154-173, November 2025. We model shifts in marriage probabilities in India’s National Family Health Survey-4 (NFHS-4) data by using the discrete time death process. We treat marriages …
Calcutta Statistical Association Bulletin, Volume 77, Issue 2, Page 139-153, November 2025. A multi-treatment two-stage adaptive design is developed for phase III clinical trials with ordinal categorical responses. Starting with an equal randomization …
