Discussion by Timothy C. Beerssome comments on the one application which they deal with, that of the velocity structure (or lack thereof) in the Coma cluster. At my request, the authors have kindly supplied me with a copy of the data set which they have used.

Some Statistical Problems in Cosmology surveys of galaxy clustering, the origins of clustering in cosmological models, galaxy correlation functions, double Poisson models, Voronoi tessellations, minimal spanning trees, and Saslaw’s distribution function.

Discussion by Suketu P. Bhavsarscusses the related practical problem of quantifying the measures of the distribution of galaxies, the visible “building blocks” of the material universe and assumed tracers of this structure. The generally accepted view is that the origin of the observed distribution of galaxies is the initial dens

I suggest three: the stochastic geometry of Boolean sets and Cox processes, the expression of image features via invariants of convolutions with derivatives of Gaussians at many different scales, and the linearized statistics of second-order symmetric

Statistical Issues Concerning Quasar Absorption Line Systems0 have now been found. The study of the distribution of their physical properties and locations in space is inherently statistical because all types of extended gaseous object can produce absorption. A variety of statistical problems are discussed, including parameter estimation and goodness of fit
