Abstract: The post-reionization (z ≤ 6) neutral hydrogen (H i ) 21-cm intensity mapping signal holds the potential to probe the large scale structures, study the expansion history and constrain various cosmological parameters. Here we apply the Tapered… read more here.

DOI: 10.1177/0013164417752008
Abstract: When item scores are ordered categorical, categorical omega can be computed based on the parameter estimates from a factor analysis model using frequentist estimators such as diagonally weighted least squares. When the sample size is… read more here.
