Results 11 to 20 of about 40 (39)
We give several new characterizations of completely monotone functions and Bernstein functions via two approaches: the first one is driven algebraically via elementary preserving mappings and the second one is developed in terms of the behavior of their ...

The de Finetti structure behind some norm-symmetric multivariate densities with exponential decay
We derive a sufficient condition on the symmetric norm ||·|| such that the probability distribution associated with the density function f (x) ∝exp(−λ ||x||) is conditionally independent and identically distributed in the sense of de Finetti’s seminal ...

Sample correlations of infinite variance time series models: an empirical and theoretical study
When the elements of a stationary ergodic time series have finite variance the sample correlation function converges (with probability 1) to the theoretical correlation function. What happens in the case where the variance is infinite? In certain cases, the sample correlation function converges in probability to a constant, but not always.

New properties and representations for members of the power-variance family.I [PDF]
We derive new Wright-function representations for the densities of the generating measures of most representatives of the power-variance family of distributions.

Computing VAR and AVaR in Infinitely Divisible Distributions
In this paper we derive closed-form solutions for the cumulative distribution function and the average value-at-risk for five subclasses of the infinitely divisible distributions: classical tempered stable distribution, Kim–Rachev distribution ...

Sharp bounds on the survival function of exchangeable min-stable multivariate exponential sequences
We derive lower and upper bounds for the survival function of an exchangeable sequence of random variables, for which the scaled minimum of each finite subgroup has a univariate exponential distribution.

Failure of the Raikov theorem for free random variables
Summary. We show that the sum of two free random variables can have a free Poisson law without any of them having a free Poisson law. Key words: free probability theory, Raikov theorem, free Poisson distribution, free convolution, R-transform.
