摘要：

We describe the issues related to the analysis of the large scale distribution of galaxies. The emerging huge data sets from wide field sky surveys pose interesting issues, both statistical and computational. One needs to reconsider the notion of optimal statistics. We discuss the power spectrum analysis of wide area galaxy surveys using the Karhunen-Loeve transform as a case study.
