Distribution of the Product of Squared Correlated Shadowed Rician Random Variables

SPIN, 2020
In this paper, we investigate the problem concerned with the distribution of the product of two squared correlated Shadowed-Rician (SR) random variables (RVs). The SR land mobile satellite (LMS) comsat can be correlated or uncorrelated.

Bivariate modelling of clustered continuous and ordered categorical outcomes.

Statistics in Medicine, 1997
Simultaneous observation of continuous and ordered categorical outcomes for each subject is common in biomedical research but multivariate analysis of the data is complicated by the multiple data types.

Product Inequalities Involving the Multivariate Normal Distribution

, 1980
Suppose Y′ = (Y′ 1, …, Y′ k ) possesses a multivariate normal distribution with mean vector 0 and positive semidefinite covariance matrix Σ. If Ci ⊂ Rpi denote convex regions symmetric about the origin, then conditions are given such that and/or obtain ...

Comment on "probability distribution of power fluctuations in turbulence".

Physical review. E, Statistical, nonlinear, and soft matter physics, 2014
Bandi et al. [Phys. Rev. E 79, 016309 (2009)] reported a closed form expression for the probability density function of the product of two correlated normal random variables and proposed an approximation for the distribution of its mean.

On the order statistics from equally correlated normal random variables

, 1973
SUMMARY 1(1)10(2)50 and p = 04100, 0-125, 0 200, 3, 0 375, 0'400, 2, 0 600, 0 625, 2, 0 700, 0 750, 0 800, 0 875, 0 900. The method of evaluation of the percentage points is discussed.

On linear functions of ordered correlated normal random variables

, 1965
Many problems of statistical inference, notably the ones in multiple decisions and life testing involve the use of ordered Xi's. In an earlier paper Gupta, Pillai & Steck (1964) considered the distribution of linear functions of X(j)'s and gave closed ...

On the distribution of linear functions and ratios of linear functions of ordered correlated normal random variables with emphasis on range

, 1964
SUMMARY This paper deals with the distribution of linear functions and ratios of linear functions of order statistics from an equally correlated set of normal random variables. Some special cases of this family of linear functions are considered.
