Discrete Mittag-Leffler distributions
R.N. Pillai,K. Jayakumar +1 more
TL;DR: In this paper, a new class of discrete distributions, namely discrete Mittag-Leffler distributions (DMLD), is introduced and its properties are studied, which are generalizations of the geometric distribution.
Journal ArticleDOI
On a generalization to Marshall–Olkin scheme and its application to Burr type XII distribution
K. Jayakumar,Thomas Mathew +1 more
TL;DR: In this article, the authors introduced the Marshall-Olkin semi-Burr and the Marshall -Olkin Burr distributions and derived their various characteristics in reliability analysis in time series analysis.
Journal ArticleDOI
The first-order autoregressive mittag-leffler process
K. Jayakumar,R.N. Pillai +1 more
TL;DR: In this article, the first-order autoregressive semi-Mittag-Leffler (SMLAR(1)) process is introduced and its properties are studied, as well as the special case of the firstorder autoresignation semi-mittag leffler process.
Journal ArticleDOI
A bivariate INAR(1) time series model with geometric marginals
TL;DR: A simple bivariate integer-valued time series model with positively correlated geometric marginals based on the negative binomial thinning mechanism and the unknown parameters are estimated using the modified conditional least squares method.
Journal ArticleDOI
On bivariate geometric distribution
TL;DR: In this paper, various bivariate geometric distributions analogous to important bivariate exponential distributions, such as, Marshall-Olkin's BGE, Downton's BBE, and Hawkes' BBE are presented.
