Abstract
This second chapter of two companion chapters on the estimation of power spectra specializes in the topic of estimating galaxy power spectra at large, linear scales using maximum likelihood methods. As in the first chapter, the aims are pedagogical, and the emphasis is on concepts rather than technical detail. The chapter covers most of the salient issues, including selection functions, likelihood functions, Karhunen–Loève compression, pair-integral bias, Local Group flow, angular or radial systematics (arising for example from extinction), redshift distortions, quadratic compression, decorrelation, and disentanglement. The procedures are illustrated with results from the IRAS PSCz survey. Most of the PSCz graphics included in this chapter have not been published elsewhere.
