Assessment of Subclustering in Clusters of Galaxies of galaxies. The importance of subclusters lies in the information they may convey concerning the formation and evolution of rich clusters of galaxies, the largest gravitationally bound structures yet discovered in the universe. A variety of methods for addressing the broad question of the existenc

Discussion by Pranab K. Senlaxies, with due emphasis on their limitations due to astronomical as well as statistical constraints. Although I endorse his views to a greater extent, I have a few dissenting comments to offer, and I shall mostly confine myself to them.

Limitations to the Method of Power Spectrum Analysis: Nonstationarity, Biased Estimators, and Weak Cicities. This method generates a sequence of random numbers from observational data which, it was claimed, are exponentially distributed with unit mean and variance, essentially . of the distribution of the original data. We show that the derived random process preserves a subtle imprint of the orig

Response by William I. Newman et al.d by astronomers Yu and Peebles two decades ago to establish the presence of periodicity and/or quantization. We have been particularly motivated by the work of Tifft, Arp and others who have claimed that quantization plays a major role in astronomy. In addition, we examined and presented recent, ac

Statistical Issues Concerning Quasar Absorption Line Systemsal distributions. We begin with an introduction to the astrophysics of the absorption systems and current research goals, which should enable the reader without an astrophysical background to work on the statistical problems posed in current research papers.
