The q-Deformed Hyperbolic Secant Family

S. A. El-SHEHAWY, E. A-B ABDEL-SALAM

Abstract



In this paper, by virtue of deformed hyperbolic functions, a q-deformed hyperbolic secant (q-DHS) distribution for the symmetric hyperbolic secant (HS (distribution is constructed. The introduced parameter q. Based on this distribution, the moment-generating function (mgf), the characteristic function (cf), the score function, the cumulant-generating function (cgf) and some corresponding important characteristics are derived. The maximum likelihood (ML) method is illustrated to determine the corresponding maximum likelihood estimates (MLE) for the introducing parameter q. According to the values of the proposed parameter, some calculations are reviewed and tabulated.

Keywords


Generalized hyperbolic functions, Generalized hyperbolic secant distribution, Hyperbolic secant distribution, Skew generalized secant distributions.
