Quasi-Bézier Curves with Shape Parameters [PDF]
Journal of Applied Mathematics, 2013 The universal form of univariate Quasi-Bézier basis functions with multiple shape parameters and a series of corresponding Quasi-Bézier curves were constructed step-by-step in this paper, using the method of undetermined coefficients. The series of Quasi-

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.

Robust estimation of shape parameters [PDF]
Procedings of the British Machine Vision Conference 1990, 1990 We investigate the use of Robust Estimation in an application requiring the accurate location of the centres of circular objects in an image. A common approach used throughout computer vision for extracting shape information from a data set is to fit a feature model using the Least Squares method.
