Modification of the halo mass function by kurtosis associated with primordial non-Gaussianity [PDF]

, 2011
We study the halo mass function in the presence of the kurtosis type of primordial non-Gaussianity. The kurtosis corresponds to the trispectrum as defined in Fourier space.

EM Algorithm in the Modified Slash Power Maxwell Distribution with an Application

Axioms
In this article, we introduce a distribution that is an extension of the Power Maxwell (PM) distribution, which is based on the quotient of two independent random variables. These are the PM and a gamma distribution, respectively. In this way, the result
