Predictions for the 21cm-galaxy cross-power spectrum observable with LOFAR and Subaru
Dijana Vrbanec, Benedetta Ciardi, Vibor Jelić +8
The 21cm-galaxy cross-power spectrum is expected to be one of the promising probes of the Epoch of Reionization (EoR), as it could offer information about the progress of reionizat…
A Bayesian analysis of redshifted 21-cm HI signal and foregrounds: Simulations for LOFAR
Abhik Ghosh, L. V. E. Koopmans, Emma Chapman +1
Observations of the EoR with the 21-cm hyperfine emission of neutral hydrogen (HI) promise to open an entirely new window onto the formation of the first stars, galaxies and accret…
Testing Composite Null Hypothesis Based on -Divergences
Abhik Ghosh, Ayanendranath Basu
We present a robust test for composite null hypothesis based on the general -divergence family. This requires a non-trivial extension of the results of Ghosh et al.~(2015). We d…
Robust Bounded Influence Tests for Independent Non-Homogeneous Observations
Abhik Ghosh, Ayanendranath Basu
Experiments often yield non-identically distributed data for statistical analysis. Tests of hypothesis under such set-ups are generally performed using the likelihood ratio test, w…
