Usage Note:The termparameter,which originates in mathematics, has a number of specific meanings in fields such as astronomy, electricity, crystallography, and statistics. Perhaps because of its ring of technical authority, people have appliedparametermore generally in recent years to refer to any fac...

If you use a local variable in a query predicate instead of a parameter or literal, the optimizer resorts to a reduced-quality estimate, or a guess for selectivity of the predicate. Use parameters or literals in the query instead of local variables, and the optimizer typically can pick a be...
Two-parametergeneralizedstatisticsThe physical meaning of the parameters (κ, ζ), emerging in the statistical theory [G. Kaniadakis, Eur. Phys. J. B70 (2009) 3; D. P. Mittal, Metrika22 (1975) 35; B. D. Sharma and I. J. Taneja, Metrika22 (1975) 205] considered by Kaniadakis, ...

Barakat [1987] derived the Stokes parameter statistics, applicable to one-look synthetic aperture radar (SAR) images, of a partially polarized wave backscattered from a Gaussian area. In this paper, the statistics of the Stokes parameter... R Touzi,A Lopes - 《IEEE Transactions on Geoscience ...
Multicollinearity results from one independent variable being accurately linearly predicted by other independent variables, which reduces the stability of parameter estimation for the affected variables. This article aims to analyze the shape of the global EKC curve under the influence of 12 additional var...
