Power of edge exclusion tests in graphical gaussian models

Salguiero, Fatima, Smith, Peter and McDonald, John (2003) Power of edge exclusion tests in graphical gaussian models , Southampton, UK Southampton Statistical Sciences Research Institute 21pp. (S3RI Methodology Working Papers, M03/02).

Record type: Monograph (Working Paper)


Asymptotic multivariate normal approximations to the joint distributions of edge exclusion test statistics for saturated graphical Gaussian models are derived. Non-signed and signed square-root versions of the likelihood ratio, Wald and score test statistics are considered. Non-central chi-squared approximations are also considered for the non-signed versions. These approximations are used to estimate the power of edge exclusion tests and an example is presented.
