Schematic of the detection inference. Given the data, d, which is the linear combination of the noise distribution, n, plus the signal, s, we can define the likelihood of detection by setting an arbitrary S/N threshold γ and integrating the probability density function of the S/N for d from γ to ∞, as indicated with the shaded area. By nullifying s through jackknifing of d, we recover the ideal thermal noise, n, and thus compute the likelihood of a false positive detection
as we do for computing
. The ratio of the two likelihoods provides the significance of detection. This figure is inspired by Fig. 1 of Vio & Andreani (2016).
