Ml Estimation and Lr Tests for the Multivariate Normal

In this study ''Ie investigate maximum likelihood (ML) estimation and likelihood ratio (LR) tests for the multivariate normal distribution with mean vector ~ and covariance matrix k following the linear structures: 11 = Xr< and ]:; = I T G , where X and G are properly defined ~ ~ .-g g~g ~ ~g known matrices, and ~ and ! = (T g) are vectors of unknown parameters. Likelihood equations are obtaine...

A Characterization of the Multivariate Normal Distribution by Using the Hazard Gradient

A b s t r a c t . We give a general result to characterize a multivariate distribution from a relationship between the left truncated mean function and the hazard gradient function. This result allows us to obtain new characterizations of multivariate distributions. In particular, we show that, for the multivariate normal distribution, the simple relationship, obtained in standardized form by M...
