Contributions to statistical analysis of astronomical data inferential issues and multivariate techniques

Abstract

Quest for the unknown has been man s outstanding intellectual asset for proliferation of newlinescientific pursuit. The vast universe all around has beckoned him from time immemorial to newlineunveil its mystery by exploring new innovations and inventions. When man had started newlinethinking about the world beyond his own earth, he had discovered the concept of another newlineworld. This is a collective world of celestial objects and astronomical objects, and newlineastronomical bodies along with the empty space of the universe. There is an amazing newlinecollection of familiar astronomical bodies like the stars, planets, and moons as well as newlinecomplex structures like painty nebulae, delicate star clusters, massive galaxies , variable newlinestars, etc., inhabiting in this Universe. newlineIf we visualize our universe as a hierarchical structure, we see that galaxies constitute the newlinefundamental ingredient of this assemblage at the largest scale. The study of the formation newlineand evolutionary histories of different galaxies and interaction with other galaxies may lead newlineto concern with the processes that developed a heterogeneous universe from a newlinehomogeneous inception. The analysis of astronomical objects namely globular clusters in a newlinegalaxy marks the beginning of a new era to explore galaxy formation in ways that are newlineunique newline
