Reanalysis of F-statistic gravitational-wave searches with the higher criticism statistic
We propose a new method of gravitational wave detection using a modified form of higher criticism, a statistical technique introduced by Donoho & Jin (2004). Higher criticism is designed to detect a group of sparse, weak sources, none of which are strong enough to be reliably estimated or detected individually. We apply higher criticism as a second-pass method to synthetic F-statistic and C-sta...
متن کاملHigher Criticism Statistic: Theory and Applications in Cosmology and Astronomy
Higher Criticism is a recent statistic proposed by Donoho and Jin [1] where it has been shown to be effective at resolving a very subtle testing problem: test whether n normal means are all zero versus the alternative that a small fraction is non-zero. Higher Criticism is also useful for non-Gaussian detection. Motivated by the recent problem of detecting cosmic strings, we consider a setting i...
متن کاملHigher Criticism Statistic: Theory and Applications in Non-gaussian Detection
Higher Criticism is a statistic recently proposed by Donoho and Jin5. It has been shown to be effective in resolving a very subtle testing problem: whether n normal means are all zero versus a small fraction is nonzero. Higher Criticism is also useful for non-Gaussian detection in Cosmic Microwave Background (CMB) data. In this report, we review the theory developed in Donoho and Jin5 and discu...
متن کاملAn improved, ‘‘phase-relaxed’’ F -statistic for gravitational-wave data analysis
Rapidly rotating, slightly nonaxisymmetric neutron stars emit nearly periodic gravitational waves (GWs), quite possibly at levels detectable by ground-based GW interferometers. We refer to these sources as ‘‘GW pulsars.’’ For any given sky position and frequency evolution, the F -statistic is the maximum likelihood statistic for the detection of GW pulsars. However, in ‘‘all-sky’’ searches for ...
متن کاملHigher Criticism Statistic: Detecting and Identifying Non-Gaussianity in the WMAP First Year Data
Higher Criticism is a recently developed statistic for non-Gaussian detection, proposed in Donoho & Jin 2004, where it has been shown to be effective at resolving a very subtle testing problem: whether n normal means are all zero versus the alternative that a small fraction is nonzero. Higher Criticism is also useful in the detection of a non-Gaussian convolution component of cosmic strings in ...
