Approximations Related to Tempered Stable Distributions

Kalyan Burman, Neelesh S Upadhye, Palaniappan Vellaisamy

In this article, we first obtain, for the Kolmogorov distance, an error bound between a tempered stable and a compound Poisson distribution and also an error bound between a temper…

Covariance Identities and Variance Bounds for Infinitely Divisible Random Variables and Their Applications

Kalyan Barman, Neelesh S Upadhye, Palaniappan Vellaisamy

In this article, we establish a general covariance identity for infinitely divisible distributions (IDD). Using this result, we derive Cacoullos type variance bounds for the IDD. A…

Subordinated Compound Poisson processes of order

Ayushi Singh Sengar, N. S. Upadhye

In this article, the compound Poisson processes of order (CPPoK) is introduced and its properties are discussed. Further, using mixture of tempered stable subordinator (MTSS) a…

Approximations Related to the Sums of -dependent Random Variables

Amit N. Kumar, Neelesh S. Upadhye, P. Vellaisamy

In this paper, we consider the sums of non-negative integer valued -dependent random variables, and its approximation to the power series distribution. We first discuss some rel…

Time-changed Poisson processes of order

Ayushi S. Sengar, A. Maheshwari, N. S. Upadhye

In this article, we study the Poisson process of order k (PPoK) time-changed with an independent Lévy subordinator and its inverse, which we call respectively, as TCPPoK-I and TCPP…
