Observations of redshift-space distortions in spectroscopic galaxy surveys offer an attractive method for observing the build-up of cosmological structure, which depends both on the expansion rate of the Universe and our theory of gravity. In this paper, we present a formalism for forecasting the constraints on the growth of structure which would arise in an idealized survey. This Fisher matrix based formalism can be used to study the power and aid in the design of future surveys.

Observational probes of cosmic acceleration (2012, methodology): “The White et al. (2009) forecasts, which assume that kmax scales with the non-linear wavelength knl(z) of the matter power spectrum, yield smaller errors at high redshift and an aggregate precision of 0.10%.”

How to evade the sample variance limit on measurements of redshift-space distortions (2008, background): “The improvement applies to the full shape of the power spectrum, Pθθ(k), not just the overall amplitude (contrary to a statement in [29]), which can be very useful for constraining modified gravity models with scale-dependent growth of structure, e.”
Galaxy And Mass Assembly (GAMA): improved cosmic growth measurements using multiple tracers of large-scale structure (2013, result): “We compared our measurements with Fisher matrix forecasts, which also indicate how our results would extend to surveys with a different design (also see McDonald & Seljak 2009; White et al. 2009; Abramo 2012).”
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: measurements of the growth of structure and expansion rate at z = 0.57 from anisotropic clustering (2012, background): “(11) Given a tight constraint on the underlying shape of the linear matter power spectrum, the two-dimensional clustering of galaxies constrains both bσ 8 and f σ 8 (Percival & White 2008; White et al. 2009).”
