A New Extended Weibull Distribution with Application to Influenza and Hepatitis Data
Stats, 2023 The Weibull is a popular distribution that models monotonous failure rate data. In this work, we introduce the four-parameter Weibull extended Weibull distribution that presents greater flexibility, thus modeling data with bathtub-shaped and unimodal ...

Tangent Topp-Leone Family of Distributions
Scientific African, 2022 We introduce the tangent Topp-Leone family of distributions in this study and derive some of its statistical properties. Further, we develop five special distributions and a location-scale regression model based on the new proposed tangent Topp-Leone ...

Kernel regression with Weibull-type tails [PDF]
Annals of the Institute of Statistical Mathematics, 2015 We consider the estimation of the tail coefficient of a Weibull-type distribution in the presence of random covariates. The approach followed is non-parametric and consists of locally weighted estimation in narrow neighbourhoods in the covariate space. We introduce two families of estimators and study their asymptotic behaviour under some conditions on

Quantile Regression with a New Exponentiated Odd Log-Logistic Weibull Distribution
Mathematics, 2023 We define a new quantile regression model based on a reparameterized exponentiated odd log-logistic Weibull distribution, and obtain some of its structural properties.

Reliability analysis of structural ceramic components using a three-parameter Weibull distribution [PDF]
, 1992 Described here are nonlinear regression estimators for the three-Weibull distribution. Issues relating to the bias and invariance associated with these estimators are examined numerically using Monte Carlo simulation methods.

Evaluation of Weibull parameters by different methods for farms
Acta Scientiarum: Technology, 2023 One of the most prevalent clean and sustainable forms of energy produced worldwide is the power created from wind runoff. Wind turbines ought to be installed in areas with favorable circumstances to transform mechanical wind energy into electricity ...

Sub-Weibull distributions: generalizing sub-Gaussian and sub-Exponential properties to heavier-tailed distributions [PDF]
, 2020 We propose the notion of sub-Weibull distributions, which are characterised by tails lighter than (or equally light as) the right tail of a Weibull distribution.

Testing homogeneity in Weibull-regression models
Biometrical Journal, 2005 In survival studies with families or geographical units it may be of interest testing whether such groups are homogeneous for given explanatory variables. In this paper we consider score type tests for group homogeneity based on a mixing model in which the group effect is modelled as a random variable.

Unit-Modified Weibull Distribution and Quantile Regression Model [PDF]
Anais da Academia Brasileira de CiênciasThe Sustainable Development Goals (SDGs) of the United Nations consist of 17 general objectives, subdivided into 169 targets to be achieved by 2030. Several SDG indices and indicators require continuous analysis and evaluation, and most of these indices ...
