TL;DR: In sequential methodologies, finally accrued data customarily look like {Nν,X1,...,XNν} where N≡Nν is the total number of observations collected through termination.
Abstract: In sequential methodologies, finally accrued data customarily look like {Nν,X1,...,XNν} where N≡Nν is the total number of observations collected through termination. Under mild regulatory condition...

TL;DR: In this paper, a two-stage SINR model for the U(q, mq) model, where m > 1 is known, is proposed, and the confidence interval is shown to be tight.
Abstract: In the literature, an extensive work on sequential fixed-width confidence interval for the parameter of U(q, mq) model, where m > 1 is known, is available. In this article, we propose a two-stage s...

TL;DR: In this paper, the authors present several approaches to estimation of survival functions of vectors of lifetimes, but some of these estimators either are inconsistent or not fully defined in range.
Abstract: At the present time there are several approaches to estimation of survival functions of vectors of lifetimes. However, some of these estimators either are inconsistent or not fully defined in range...

TL;DR: In this paper, the nonparametric regression of a response variable on a binary treatment and a control covariate is defined as the regression of the response on the control plus the conditional variable.
Abstract: The nonparametric regression of a response variable on a binary treatment and a control covariate equals the nonparametric regression of the response on the control plus the conditional (given the ...

TL;DR: In this paper, the estimation of R = P(Y < X) is considered when X and Y are two independent generalized Pareto distributions and the maximum likelihood estimators and Bayes estimators of R are obtained.
Abstract: In this article, the estimation of R=P(Y
TL;DR: In this paper, the authors analyzed various patterns in the pollution levels of PM10, PM2.5, NO2, and SO2 at various locations in Kolkata, India.
Abstract: This article analyses various patterns in the pollution levels of PM10, PM2.5, NO2, and SO2 at various locations in Kolkata, India. Our analysis is based on a data set recorded by the Central Pollu...
TL;DR: In this paper, the authors compared two approaches within the maximum likelihood estimation (MLE) framework for estimating the normal mean (μ) under right censoring (threshold = M, σ is known).
Abstract: For efficiently estimating the normal mean (μ) under right censoring (threshold =M, σ is known), we compare two approaches within the maximum likelihood estimation (MLE) framework. Approach I is a ...
TL;DR: In this article, nonparametric test procedures for comparing effects of two treatments in two period parallel group design are presented, where each subject receives the same treatment over the two periods.
Abstract: This work deals with nonparametric test procedures for comparing effects of two treatments in two period parallel group design, where each subject receives the same treatment over the two periods. ...
