Recent years have seen a veritable surge in the popularity of social media micro-influencers among the younger generations like Millennials and Generation-Z. These amateur micro-influencers have achieved a modicum of fame through their charismatic appeal and niche expertise, by focusing on a...

We examine the rate of decay to the limit of the tail dependence coefficient of a bivariate skew-t distribution. This distribution always displays asymptotic tail dependence. It contains as a special case the usual bivariate symmetric t distribution, and hence is an appropriate (skew) extension....

This is particularly important if one can specify a model in...

The Generalised Normal Variance–Mean (GNVM) model in which the mixing random variable is Gamma distributed is considered. This model generalises the popular Variance-Gamma (VG) distribution. This GNVM model can be interpreted as the addition of noise to a (skew) VG base. The discussion is...

We derive the rate of decay of the tail dependence of the bivariate normal distribution and establish its link with regularly varying functions. This result is an initial step in explaining the discrepancy between a zero asymptotic tail dependence coefficient and mass in the tail of a joint...

We examine two bivariate skew t distributions, both of which generalize the bivariate symmetric t distribution. The second, based on the bivariate skew normal distribution, always displays positive asymptotic lower tail dependence. The difference is associated with the varying tail behavior of...

The GGH family of multivariate distributions is obtained by scale mixing on the Exponential Power distribution using the Extended Generalised Inverse Gaussian distribution. The resulting GGH family encompasses the multivariate generalised hyperbolic (GH), which itself contains the multivariate t...
