Semi-parametric models for the intensities of the traumatic failures are used supposing that these intensities depend on degradation level. Semi-parametric estimators of various reliability characteristics are proposed and asymptotic properties of the estimators are obtained. The theoretical results are ...
There are a lot of statistical analyses that can be performed on data sets. In MATLAB, the statistical functions are in the data analysis help topic called datafun. Statistics can be used to characterize properties of a data set. For example, consider a set of exam grades {33, 75, 77, ...
In this paper, we introduce a new form of distributions called ”Marshall-Olkin Extended Weibull distribution” MOEW. We study some of its structural properties and the shape of its hazard rate function. We provide some methods of point estimation for the unknown parameters and discuss its asympt...
it is usually called reliability analysis. Survival analysis emphasizes a nonparametric estimation approach (Kaplan-Meier estimation), while reliability analysis emphasizes a parametric approach (Weibull or lognormal estimation). In the rest of this chapter, when we refer to survival analysis, you can ...

“Unit-Weibull distorted copulas”, the UW distorted copula distribution and its corresponding conditional and density distributions are formulated. Examples and possible limiting cases in parameters are presented. “Properties” investigates properties such as the tail dependence coefficients, tail orders, ...
A New Burr XII-Weibull-Logarithmic Distribution for Survival and Lifetime Data Analysis: Model, Theory and Applications A new compound distribution called Burr XII-Weibull-Logarithmic (BWL) distribution is introduced and its properties are explored. This new distribution contains several new and well ...
Statistics used for point estimation of unknown quantities in the population are called estimators. (Numerical values of the latter are called estimates.) Some requirements on ‘good’ estimators are mentioned, such as being unbiased, consistent and having small variance. Four general methods for ...
is to find the best R2 for logistic regression. Your move from Cox-Snell (R2CS) to McFadden (R2MF) and then to Tjur (R2Tjur) explains that. Of course, R2Tjur has a lot of intuitive appeal, and it easy to calculate (plus some other useful properties, like independence of the base ...
