On the Three-Parameter Weibull Distribution Shape Parameter Estimation [PDF]
Journal of Data Science, 2021 The Weibull distribution has received much interest in reliability theory. The well-known maximum likelihood estimators (MLE) of this fam- ily are not available in closed form expression. In this work, we propose a consistent and closed form estimator for shape parameter of three-parameter Weibull distribution.

A Direct Prediction of the Shape Parameter in the Collocation Method of Solving Poisson Equation
Mathematics, 2022 In this paper, we totally discard the traditional trial-and-error algorithms of choosing the acceptable shape parameter c in the multiquadrics −c2+∥x∥2 when dealing with differential equations, for example, the Poisson equation, with the RBF collocation ...

Port-Estimation of a Shape Second-Order Parameter
Revstat Statistical Journal, 2014 In this paper we study, under a semi-parametric framework and for heavy right tails, a class of location invariant estimators of a shape second-order parameter, ruling the rate of convergence of the normalised sequence of maximum values to a non ...

Particle shape analysis of clay based on digital image technology
Yantu gongcheng xuebao, 2020 The macro-physical and mechanical properties of clay are closely related to its micro-particle shape. The typical soft clay in Tianjin Port area of China is taken as the research object, and its particle shape characteristics are analyzed and studied by ...

Mathematics, 2023 We propose a joint optimization algorithm that combines the optimal shape parameter–Gaussian radial basis function (G-RBF) surrogate model with global and local optimization techniques to improve accuracy and reduce costs.

Lifetime Models with Nonconstant Shape Parameters
Revstat Statistical Journal, 2003 In its standard form, a lifetime regression model usually assumes that the time until an event occurs has a constant shape parameter and a scale parameter that is a function of covariates. In this paper we consider lifetime models with shape parameter dependent on a vector of covariates.

Curvature based characterization of radial basis functions: application to interpolation
Mathematical Modelling and Analysis, 2023 Choosing the scale or shape parameter of radial basis functions (RBFs) is a well-documented but still an open problem in kernel-based methods. It is common to tune it according to the applications, and it plays a crucial role both for the accuracy and ...
