We present a simple statistic, calculated from either complete failure data or from right-
censored data of type-I or-II. It is useful for understanding the behavior of the parameter …

This thesis will investigate the effect of differing assumed frailty models on the corresponding
estimated regression coefficients. The main purpose of the Cox model in survival analysis is …

The multivariate Weibull distribution often provides a point of departure for modelling
repeated, or a sequence of, failure times for a particular individual. It is then natural to want …

The estimation of the reliability function of the Weibull lifetime model is considered in the
presence of uncertain prior information (not in the form of prior distribution) on the parameter …

The Weibull distribution has received much interest in reliability theory. The well-known
maximum likelihood estimators (MLE) of this family are not available in closed form …

The Weibull distribution, frequently used for life data analysis, is composited with inverse
Weibull distribution to obtain a computationally convenient parametric distribution for …

There are many real-life situations where exact failure times are not available or not easily
available for reliability analysis. Motivated by this problem, this work is concerned with the …

The estimation of reliability P (X> χ 0) is considered in the case of (1) N (μ, 1),(2) N (μ, σ
2),(3) E (X; λ, θ), an exponential distribution with two parameters. Five estimators are …

The stress–strength model is one of the models that are used to compute reliability. In this
paper, we derived mathematical formulas for the reliability of the stress–strength model that …

In reliability engineering, the Weibull distribution is one of the most widely used distributions
for modelling lifetime data. Often when analyzing experimental data, it is important to …
