Inferences and Optimal Censoring Schemes for Progressively First-Failure Censored Nadarajah-Haghighi Distribution
A new extension of the exponential distribution, proposed by Nadarajah and Haghighi (Statistics 45 , 543–558 (
2011 )), is an alternative to the gamma,...

A Skewed Nadarajah–Haghighi Distribution with Some Applications
In this paper, we introduce a new skewed distribution based on the Nadarajah–Haghighi distribution, with a skewed mechanism using the logistic...

Statistical Analysis of Improved Type-II Adaptive Progressive Hybrid Censored NH Data
Recently, improved Type-II adaptive progressive censoring has been introduced to ensure that the experimental duration does not exceed a certain time...

The inverted exponentiated Chen distribution with application to cancer data
This article defines a new inverted exponentiated Chen (IEC) distribution, which has upside-down bathtub shape and increasing hazard function. A...

Inference for a constant-stress model under progressive type-II censored data from the truncated normal distribution
In this study, constant-stress accelerated life testing has been investigated using type-II censoring of failure data from a truncated normal...

The Log-Logistic Regression Model Under Censoring Scheme
A regression model, based on the well-known log-logistic distribution is proposed. This model is parameterized in terms of the median of the...

On the distribution of the sum of independent and non-identically extended exponential random variables
Considering the sum of the independent and non-identically distributed random variables is a most important topic in many scientific fields. An...

A note on a measure of asymmetry
A recently proposed measure of asymmetry (Patil et al. in Stat Papers 53: 971–985, 2012) is analyzed in detail. Several examples illustrate the...

Estimation in constant-stress accelerated life tests for extension of the exponential distribution under progressive censoring
In this paper, constant-stress accelerated life test is assumed when the lifetime of test units follows an extension of the exponential distribution....

Record values from NH distribution and associated inference
A new extension of exponential distribution, called NH distribution, was recently introduced by Nadarajah and Haghighi (Statistics 45:543–558,
2011 ).... -
An ‘apples to apples’ comparison of various tests for exponentiality
The exponential distribution is a popular model both in practice and in theoretical work. As a result, a multitude of tests based on varied...

An extended-G geometric family
AbstractWe introduce and study the extended-G geometric family of distributions, which contains as special models some important distributions such...

Asymptotic efficiency of new exponentiality tests based on a characterization
Two new tests for exponentiality, of integral- and Kolmogorov-type, are proposed. They are based on a recent characterization and formed using...

Generalized Weibull Distributions
Since 1970’s, many extensions of the Weibull distribution have been proposed to enhance its capability to fit diverse lifetime data and Murthy et...

The Marshall-Olkin extended Weibull family of distributions
We introduce a new class of models called the Marshall-Olkin extended Weibull family of distributions based on the work by Marshall and Olkin...
