Quality and Reliability Engineering International, 2004
AbstractThis paper proposes a simple and exact method for conducting a statistical test about the shape parameter of the new two‐parameter lifetime distribution with a bathtub‐shaped or increasing failure rate function, as well as an exact confidence interval for the same parameter. The necessary critical values of the test are given.

Learning Shape Trends: Parameter Estimation in Diffusions on Shape Manifolds
2017 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2017Learning the dynamics of shape is at the heart of many computer vision problems: object tracking, change detection, longitudinal shape analysis, trajectory classification, etc. In this work we address the problem of statistical inference of diffusion processes of shapes.

Equivalent Gini coefficient, not shape parameter!
Scientometrics, 2022In a recent contribution in this journal, Gagolewski et al. (Scientometrics 127(5): 2829– 2845, 2022) study a new model for representing a rank size distribution – the so-called 3DSI (3 dimensions of scientific impact) model. The model depends on three parameters/dimensions: the total number of papers, the total number of citations and a third ...

Laser beam shape invariance parameters
Proceedings of LFNM 2002. 4th International Workshop on Laser and Fiber-Optical Networks Modeling (IEEE Cat. No.02EX549), 2003Quantitative characterization of laser beam intensity distribution shape is of great importance for beams comparison, to analyze their transformation along the propagation path or as criteria for DOE synthesis. One important application is distinguishing between the near field, Fresnel and Fraunhofer diffraction zones.

Optimization of Elastomer Bumper Shape Parameters
SAE Technical Paper Series, 1998<div class="htmlview paragraph">A calculation method of searching of optimum elastomer bumper shape is presented. The optimization criteria connected with static response curve are chosen. The optimization is carried out using polynomial approximation of an aid criterion and functional restrictions basing on calculations in specially chosen ...

On testimating the weibull shape parameter
Communications in Statistics - Simulation and Computation, 1990A well-known estimator for the shape parameter of a two-parameter Weibull distribution from a failure-censored sample involves a preliminary test of aa null hypothesis concerning the parameter. Efficiency of the resulting testimator varies with the chosen level of significance of the test.

Shape parameters measurement of ultralight mirrors
Optik, 2010Abstract Two measuring techniques are presented in this paper. These techniques are able to measure and process the shape of the reflecting surfaces. In the first part of the paper the theory and modifications of the optical, mechanical and software design for the Hartmann wavefront analyzer are described.

On Families of Distributions with Shape Parameters
International Statistical Review, 2014SummaryUnivariate continuous distributions are one of the fundamental components on which statistical modelling, ancient and modern, frequentist and Bayesian, multi‐dimensional and complex, is based. In this article, I review and compare some of the main general techniques for providing families of typically unimodal distributions on with one or two ...

Acquisition Curves, Shapes, and Parameters
1987There are a number of practical reasons for knowing shape, level and other parameter information about acquisition functions. Among these are: a. Estimating ultimate proficiency in a skill (eventual asymptote) for groups trained in different ways or for which it is not desired or possible to continue training for long periods.
