Journal ArticleDOI
Series Expansion for a Hypergeometric Function of Matrix Argument with Applications
TL;DR: In this paper, a series expansion is obtained for the confluent hypergeometric function of the second kind when the argument is a 2 times 2 positive definite matrix, and applications are made to the distributions of Hotelling's generalized T02 statistic, and the smallest latent root of the covariance matrix.
Journal ArticleDOI
Testing optimality of experimental designs for a regression model with random variables
TL;DR: In this article, the authors extend Tsukanov's results by computing E(detHp), where Hp is the covariance matrix of p, the l.i.d. of p and considering the optimality in the mean for the largest root criterion.
Journal ArticleDOI
A General Class of Distributions: Properties and Applications
TL;DR: In this paper, a general class of distributions and its relationship to χ2 distribution is derived and applied to a variety of applications, including normal, inverse Gaussian, lognormal, gamma, Rayleigh, and Maxwell distributions.
Journal ArticleDOI
A weighted version of Gamma distribution
Journal ArticleDOI
A comparison of some estimators of the variance covariance matrix when the population mean is known
TL;DR: In this article, the problem of estimation of variance covariance matrix of a normally distributed population, when the population mean is known, was considered and the maximum likelihood estimators derived under the known as well as unknown mean assumptions were compared under various loss functions.
