Modern astronomy has been rapidly increasing our ability to see deeper into the Universe, acquiring enormous samples of cosmic populations. Gaining astrophysical insights from these data sets requires a wide range of sophisticated statistical and mac

A family of measures on the set of permutations of the first $n$ integers, known as Ewens sampling formula, arises in population genetics. In a series of papers, the first two authors have developed necessary and sufficient conditions for the weak co

Edgeworth expansions for compound Poisson processes and the bootstrap

Autor: Kesar Singh, Yaning Yang, Gutti Jogesh Babu

Publikováno v: Annals of the Institute of Statistical Mathematics. 55:83-94

One-term Edgeworth Expansions for the studentized version of compound Poisson processes are developed. For a suitably defined bootstrap in this context, the so called one-term Edgeworth correction by bootstrap is also established. The results are app

The Ewens sampling formula in population genetics can be viewed as a probability measure on the group of permutations of a finite set of integers. Functional limit theory for processes defined through partial sums of dependent variables with respect

Spatial point processes in astronomy

Autor: Eric D. Feigelson, Gutti Jogesh Babu

Publikováno v: Journal of Statistical Planning and Inference. 50:311-326

We review several topics arising in astronomical research where the statistical analysis of spatial point processes plays a central role in scientific investigations. These include: the distribution of stars in the Milky Way; the distribution of gala
