...Another closed skew-normal distribution, which was introduced in Arellano-Valle & Azzalini (2006), follows also as a FUSN when ∆ = AΩU and ΩV = Ψ + AΩUA in (12)....

...The special case of the multivariate skew-t distribution that follows when G is the IG(ν/2, ν/2) distribution is studied in Arellano-Valle & Azzalini (2006)....

...Finally, we note that this approach was simply the starting point for Azzalini (1985)....

...If in additionp = 1, then (25) reduces to the pdf of the seminal univariate skew-normal distribution of Azzalini (1985, 1986); see also Gupta & Chen (2004) for a slightly different definition of a multivariate skewnormal distribution....

...A fundamental property of all the selection distributions satisfyingP(U ∈ C) = 1/2 has been mentioned extensively in the literature, see, e.g., Azzalini (2005), Azzalini & Capitanio (2003), Genton (2005), Genton & Loperfido (2005), Wang, Boyer & Genton (2004b) for recent accounts....

...In particular, ifU is a random vector in theC-class, thenFU(0) = 2−q and (28) yields fX(x) = 2 qfV(x)FT(w(x)), (29) which is an extension of a similar result given by Azzalini & Capitanio (1999, 2003)....

...…is discussed in Azzalini & Capitanio (2003), who have shown that they are equivalent in many important cases, like the skew-t(ST) distribution studied by Branco & Dey (2001) and Azzalini & Capitanio (2003), and extended forq > 1 in Arellano-Valle & Azzalini (2006) as a member ofSUE distributions....

...The pdf of a skew-symmetric distribution based on (2) then takes the form fX(x) = 2fV(x)π(x), (23) which is similar to the formulation in Azzalini & Capitanio (2003) except for a different but equivalent representation ofπ(x)....

...It is currently the subject of vigorous research efforts and recent advances on this topic include work by Azzalini (2005), Azzalini & Capitanio (1999, 2003), DiCiccio & Monti (2004), Ma, Genton & Tsiatis (2005), Ma & Hart (2006), Pewsey (2000, 2006), and Sartori (2006)....
