New statistical approaches
to large-scale structure
Peter Coles (Nottingham)
The data explosion currently engulfing cosmology puts pressure on
traditional methods of statistical analysis. The Sloan Digital Sky
Survey and the 2DF redshift survey will catalogue more than a million
galaxy redshifts and positions, while MAP and Planck will map the
microwave sky with arc-minute scale resolution. Simple second-order
statistics, such as the power-spectrum, are blunt instruments that
cannot do justice to the quantity and quality of these data. In this
talk I will review some of the shortcomings of traditional statistical
approaches and explore some novel techniques that can be applied
either to redshift surveys or to the microwave background.
