Abstract Various types of censoring schemes basically type-I and type-II their modified versions are used in life testing experiments. Most the tests experiments based on a single sample. A joint scheme is quite useful conducting comparative products from different units within same facility. In this article, we consider two exponential time models under multiply scheme, which generalization us...

Heavy-tailed random samples, as well their sum or average, are encountered in a number of signal processing applications radar, communications, finance, and natural sciences. Modeling such data through the Pareto distribution is particularly attractive due to its simple analytical form, but may lead infinite variance and/or mean, which not physically plausible: fact, samples always bounded prac...

We investigate an inverse censoring weighted estimator of a survival function when the data are doubly censored but the left censoring is always observed. The estimator reduces to its right censored version when there is no left censoring.

In medicals sciences and reliability engineering, the failure of individuals or units (I/Us) occurs due to independent causes failure. general, symmetry between dependent is essential nature problem at hand. this study, we considered accelerated competing risks model when lifetime I/Us was modeled using a generalized half-logistic distribution. The data were obtained with respect constant stres...

ed on a progressively type-II censored sample from the exponential distribution with unknown location and scale parameter, confidence bands are proposed for underlying function by using regions parameters Kolmogorov–Smirnov type statistics. Simple explicit representations boundaries coverage probabilities of analytically derived, performance is compared in terms band width area means data examp...

The standard Tobit maximum likelihood estimator under zero censoring threshold produces inconsistent parameter estimates, when the constant censoring threshold γ is nonzero and unknown. Unfortunately, the recording of a zero rather than the actual censoring threshold value is typical of economic data. Non-trivial minimum purchase prices for most goods, fixed cost for doing business or trading, ...

Modeling competing failure modes is an important problem in engineering and survival analyses. Competing are partially observed many applications often pose a modeling challenge. This study discusses the inference for assuming Burr XII distribution. In particular, we consider two modes, time data collected under hybrid type I censoring scheme. The model parameters estimated using maximum likeli...
