Estimating the cross-correlation power spectra of cosmic microwave background (CMB), in particular, T B and EB spectra, is important for testing parity symmetry cosmology diagnosing insidious instruments systematics. The Quadratic Maximum Likelihood (QML) estimator provides optimal estimates but it computationally very expensive. hybrid pseudo-Cl fast performs poorly on large scales. As a natur...

This article provides results on the validity of bootstrap inference methods for two-stage quasi-maximum likelihood estimation involving time series data, such as those used multivariate volatility models or copula-based models. Existing approaches require researcher to compute and combine many first- second-order derivatives, which can be difficult do is susceptible error. Bootstrap are simple...

In this paper a new method of introducing an additional parameter to a continuous distribution is proposed, which leads to a new class of distributions, called the weighted exponentiated family. A special sub-model is discussed. General expressions for some of the mathematical properties of this class such as the moments, quantile function, generating function and order statistics are derived;...
