“…As pointed out and proved by Joag-Dev and Proschan (1983), a number of well-known multivariate distributions possess the NA property, such as multinomial, convolution of unlike multionmial, multivariate hypergeometric, Dirichlet, permutation distribution, negatively correlated normal distribution, random sampling without replacement and joint distribution of ranks. For more details about NA random variables, one can refer to Matula (1992), Shao (2000), Chen et al (2008), Ling (2008), Liang and Zhang (2010), Sung (2011), Zarei and Jabbari (2011), Hu (2012, 2014), Wang et al (2011Wang et al ( , 2014a, and so on.…”
