Improved Likelihood Ratio Statistics for Covariance Selection Models

Biometrika, 1985
SUMMARY The expected value of the likelihood ratio statistic for covariance selection models, when this statistic has a closed form, is derived correct to terms of order n- 2, n being the sample size. Then a Bartlett-type correction factor is available for such statistics. By simulation, the practical use of such a correction factor is illustrated, and

Small sample statistics for likelihood-ratio tests

The Journal of the Acoustical Society of America, 1979
Classification by likelihood ratio of a one-dimensional random variate drawn randomly and with equal probability from one of two independent Gaussian populations is known to be optimal if misclassification costs are equal and statistics (true means and variances) are available; the expected classification error is then a known function of the ...

Similar Tests and the Standardized Log Likelihood Ratio Statistic

Biometrika, 1986
When testing an affine hypothesis in an exponential family the 'ideal' procedure is to calculate the exact similar test, or an approximation to this, based on the conditional distribution given the minimal sufficient statistic under the null hypothesis.

Likelihood ratios in asymptotic statistical theory

2010
This thesis deals with two topics in asymptotic statistics. A concept of asymptotic optimality for sequential tests of statistical hypotheses is introduced. Sequential Probability Ratio Tests are shown to have asymptotic optimality properties corresponding to their usual optimality properties. Secondly, the asymptotic power of Pearson's chi-square test

A Normal Approximation for the Multivariate Likelihood Ratio Statistics

1981
For many multivariate hypotheses, under the normality assumptions, the likelihood ratio tests are optimal in the sense of having maximal exact slopes. The exact distributions needed for implementing these tests are complex and their tabulation is limited in scope and accessibility.
