Statistics

Scientific paper

Often only a relatively small number of sources of a given class are detected in X-ray surveys, requiring careful handling of the statistics. We previously addressed this issue in the case of the luminosity function of normal/starburst galaxies in the GOODS area by fitting the luminosity functions using Markov-Chain Monte Carlo simulations. We are expanding on this technique to include uncertainties in the redshifts (often photometric) and uncertainties in the spectral energy distributions of the sources. We will also be performing a Bayesian analysis of the correlations between X-ray emission and fluxes from other bands (particularly radio, IR and optical/NIR) and also between X-ray luminosity and star-formation rate and stellar mass estimates. We will discuss our current results and progress to date, including also the impact of the additional 1 Ms of CDF-S data.
