  1. Complete Left Tail Asymptotic for the Density of Branching Processes in the Schröder Case

    For the density of Galton-Watson processes in the Schröder case, we derive a complete left tail asymptotic series consisting of power terms...

  2. Asymptotics for the joint tail probability of bidimensional randomly weighted sums with applications to insurance

    This paper studies the joint tail behavior of two randomly weighted sums ∑ i =1 m Θ i X i and ∑ j =1 n θ j Y j for some m, n ∈ ℕ ∪{∞}, in which the primary...

  5. On asymptotic ruin probability for a bidimensional renewal risk model with dependent and subexponential main claims and delayed claims

    In this paper, we consider a bidimensional renewal risk model with dependent main claims and delayed claims. Concretely, suppose that an insurance...

    Article 30 August 2023
  7. Strong stochastic flocking with noise under long-range fat tail communication

    Consider the reality that flocking behavior is affected by random noise. We study the Cucker–Smale-type systems with multiplicative noise where the...

  8. A New Regularly Varying Discrete Distribution Generated by Waring-Type Probability

    Abstract

    In this paper, based on the discretization method, we construct a new 2-parameter regularly varying discrete distribution generated by...

    Article 25 April 2024
  9. ON THE DISCRETE DISTRIBUTION GENERATED BY LEVY PROBABILITY

    In this paper, we consider one-parameter regularly varying discrete distribution generated by Levy probability (RDLP). Some useful plots of the...

    Article 13 January 2024
  10. Probability

    The study of probability arose out of the desire to understand (and perhaps gain an upper hand in) games of chance and gambling. Today, probability...

  13. Regression estimators for the tail index

    We propose a class of weighted least squares estimators for the tail index of a distribution function with a regularly varying tail. Our approach is...
