نویسندگان
چکیده
This work includes a new characterization of the multivariate normal distribution. In particular, it is shown that positive density function f Gaussian if and only ( x + y ) / convex in for every . result has implications to recent research regarding inadmissibility test studied by Moran (1973).

Light traffic derivatives via likelihood ratios
Ahstruct -We consider the steady-state behavior of open queueing systems with Poisson arrival processes in light traffic, that is, as the arrival rate tends to zero. We provide expressions for the derivatives with respect to the arrival rate of various quantities of interest (such as moments of steady-state sojourn times and queue lengths) evaluated at an arrival rate of zero. These expressions...
متن کاملAsymptotic normality and analysis of variance of log-likelihood ratios in spiked random matrix models
The present manuscript studies signal detection by likelihood ratio tests in a number of spiked random matrix models, including but not limited to Gaussian mixtures and spiked Wishart covariance matrices. We work directly with multi-spiked cases in these models and with flexible priors on the signal component that allow dependence across spikes. We derive asymptotic normality for the log-likeli...
متن کاملAsymptotic normality of the maximum likelihood
We present conditions to obtain the asymptotic normality of the maximum likelihood estimator of a loss process presented in [2]. We shall use the notations of [2], write ‖ · ‖q for the standard L norm on an arbitrary space R, d ≥ 1, and let D φ denote the k−th order di erentiation with respect to φ. Let us introduce the following hypotheses: (A4) For all i ∈ {1, . . . , r}, λi(Φ0) > 0. (A5) For...
متن کاملInferences for Likelihood Ratios
Likelihood ratios are extensively used to evaluate the performances of diagnostic tests and to update prior odds of disease to posttest odds. Since few tests are truly 100% accurate, including many used as “gold standards,” it is important to be able to estimate likelihood ratios in cases where no such standard is available. In this paper, methods to calculate point and interval estimates for l...
متن کاملAn Empirical Likelihood Ratio Test for Normality
The empirical likelihood ratio (ELR) test for the problem of testing for normality is derived in this paper. The sampling properties of the ELR test and four other commonly used tests are provided and analyzed using the Monte Carlo simulation technique. The power comparisons against a wide range of alternative distributions show that the ELR test is the most powerful of these tests in certain s...
