Rényi entropy, Rényi divergence and Jensen-Rényi information generating functions, and associated properties and estimation

In this paper, we propose R\'enyi information generating function (RIGF) and discuss its various properties. The relation between the RIGF and Shannon entropy of order $q>0$ is established. Several bounds are obtained. The RIGF of escort distribution is also derived. Furthermore, we introduce R\'enyi divergence information generating function (RDIGF) and discuss its effect under monotone transformations. Next, we propose Jensen-R\'enyi information generating function (JRIGF) and establish its properties. In addition, we present non-parametric and parametric estimators of the RIGF. For illustrative purpose, a simulation study is carried out and a real data relating to the failure times of electronic components is analyzed. Finally, a comparison study between the non-parametric and parametric estimators is made in terms of absolute bias and mean square error (MSE).
