Estimation of the pareto shape parameter

Communications in Statistics - Simulation and Computation, 2000
The generalized jackknife is used to reduce the bias of an estimator, based on frequency moments, of the Pareto shape parameter. Computations of amount of bias reduction and simulations of mean-squared errors are presented.

B-spline with shape parameter

2010 3rd International Conference on Advanced Computer Theory and Engineering(ICACTE), 2010
The basis function of B-spline of n order is extended to contain shape control parameter by integral, so that the shape of the constructed curve can be adjusted by changing the parameter value and it possesses the structure and geometry properties analogous to B-spline curve.

On testing a shape parameter in the presence of a location and a scale parameter

Series Statistics, 1978
A test on a shape parameter in the presence of two nuisance parameters (a location parameter μ and a scale parameter σ)is proposed. Explicit formulas and approximations are given for three applications where the general and restricted distributions are:Student-vs-Gauss-distribution, λ-vs logistic distribution, and type Iior III vs.

Estimation of the shape parameter for the three-parameter Weibull distribution

Journal of Information and Optimization Sciences, 2001
We propose the approximate maximum likelihood estimator (AMLE) for the shape parameter β in the three-parameter Weibull distribution based on Type-II right censored samples.

Parameter Estimation of the Shape Parameter of the Castillo–Hadi Model

Communications in Statistics - Theory and Methods, 2005
Abstract In Castillo and Hadi [Castillo, E., Hadi, A. S. (1995). Modeling lifetime data with application to fatigue models. J. Amer. Statist. Assoc. 90:1041–1054], a new model for the analysis of lifetime data in the presence of a covariate is presented. The model is derived based on physical and statistical considerations. In this article, we focus on

Parameter-free modelling of 2D shapes with ellipses

Pattern Recognition, 2016
Our goal is to represent a given 2D shape with an automatically determined number of ellipses, so that the total area covered by the ellipses is equal to the area of the original shape without any assumption or prior knowledge about the object structure.

Geometric Continuity and Shape Parameters

2013
Given the two curves Q 1(u) and Q 2(u), consider the joint \(\frac{{{\text{Q}}_1 \left( u \right)}} {{{\text{Q}}_2 \left( u \right)}}\). Recalling equation (4.1), continuity of the unit tangent vector is achieved if $$\frac{{{\text{Q}}_1^{\left( 1 \right)} \left( 1 \right)}} {{\left| {{\text{Q}}_1^{\left( 1 \right)} \left( 1 \right)} \right ...

Likelihood-Based Inference for the Shape Parameter of a Two Parameter Weibull Distribution

Lifetime Data Analysis, 2004
Based on a Type 2 censored sample, we use the likelihood-based approach to draw likelihood inference on the shape parameter gamma of a two-parameter Weibull distribution. In particular, we derive the profile, conditional and marginal likelihoods of gamma. Numerical results along with some concluding remarks regarding the use of likelihood-based methods
