Beam normal spin asymmetry in the quasi-RCS approximation [PDF]
, 2005 The two-photon exchange contribution to the single spin asymmetries with the spin orientation normal to the reaction plane is discussed for elastic electron-proton scattering in the equivalent photon approximation.

A comparison of strategies for Markov chain Monte Carlo computation in quantitative genetics
Genetics Selection Evolution, 2008 In quantitative genetics, Markov chain Monte Carlo (MCMC) methods are indispensable for statistical inference in non-standard models like generalized linear models with genetic random effects or models with genetically structured variance heterogeneity ...

The discount version of large deviations for a randomly indexed sum of random variables
Lietuvos Matematikos Rinkinys, 2011 In this paper, we consider a compound random variable Z = \sum^N_{j=1} vjXj , where 0 < v < 1, Z = 0, if N = 0. It is assumed that independent identically distributed random variables X1,X2, . . .

On the transport of charged particles in turbulent fields: comparison of an exact solution with the quasilinear approximation [PDF]
, 1973 The problem of charged-particle transport in a magnetic field which is solely a function of time is solved. The solution is obtained exactly, to all orders in the field, in the limit of large wavelengths normal to the magnetic field. It is shown that the

Asymptotic expansion in approximation by normal law
Lietuvos Matematikos Rinkinys, 2011 We consider the asymptotic behavior of the convolution P*n(A\sqrt{n}) of a k-dimensional probability distribution P(A) as n \to \infty for A from the \sigma-algebra M of Borel subsets of Euclidian space Rk or from its subclasses.

A logistic approximation to the cumulative normal distribution
Journal of Industrial Engineering and Management, 2009 This paper develops a logistic approximation to the cumulative normal distribution. Although the literature contains a vast collection of approximate functions for the normal distribution, they are very complicated, not very accurate, or valid for only a

Parameter Estimation in Gamma Mixture Model using Normal-based Approximation [PDF]
Journal of Statistical Theory and Applications (JSTA), 2016 Gamma mixture models have wide applications in hydrology, finance and reliability. Parameter estimation in this class of models is a challenging task owing to the complexity associated with the model structure. In this paper, a novel approach is proposed
