We compare a set of semi-numerical simulations with a radiative transfer simulation of the epoch of reionization (EoR) in their ability to predict the redshifted 21-cm signal from the neutral hydrogen (H I ) in this epoch. Specifically we compare how well they can mimic various redshift space observables of the 21-cm signal from this epoch.
