On the Asymptotic Behavior of Tails of Scale Mixtures of Normal Distributions

Journal of Mathematical Sciences, 2016
The relation between the limit behavior of the tails of the mixing distribution and that of the corresponding mixture of normal distributions is investigated. Three alternative ways of tail decay are considered.

Moments of scale mixtures of skew-normal distributions and their quadratic forms

Communications in Statistics - Theory and Methods, 2016
ABSTRACTWe obtain the first four moments of scale mixtures of skew-normal distributions allowing for scale parameters. The first two moments of their quadratic forms are obtained using those moments. Previous studies derived the moments, but all relevant results do not allow for scale parameters.

Error bounds for asymptotic expansion of the scale mixtures of the normal distribution

Annals of the Institute of Statistical Mathematics, 1987
Let X be a standard normal random variable and let \(\sigma\) be a positive random variable independent of X. The distribution of \(\eta =\sigma X\) is expanded around that of N(0,1) and its error bounds are obtained. Bounds are given in terms of \(E(\sigma^ 2\vee \sigma^{-2}-1)^ k\), where \(\sigma^ 2\vee \sigma^{-2}\) denotes the maximum of the two ...
