LIT-367: Calculation of signal detection theory measures

1 min read

Properties5
StatusActive — read in full 2026-09-30 (NOTE-314); worth reading as the standard short, citable reference for how the SDT measures are computed and what each assumes. It is a tutorial with no new theory. Several of its software pointers (1999 FTP sites, Quattro Pro, SYSTAT commands) are dated, but the formulae are not.

Cited as “source” byTHEORY-031 — The likelihood-ratio detector is optimal under the payoff, Neyman–Pearson and posterior criteria, which differ only in its threshold, so performance is an ROC and the criterion a point on it; d′ is criterion-free only for equal-variance normal signal and noise

Standing in the record

Filed on 2026-09-30 at the owner’s request, as one of the sources registered to cover signal detection theory, which the record lacked; its only detection-theory entry, Van Trees 1968 (LIT-351), is unreachable. published: is the first appearance (ADR-002).

It was filed Deferred, unread. NOTE-314 is the close reading of 2026-09-30, and it placed the work: Active — worth reading as the standard short, citable reference for how the SDT measures are computed and what each assumes. It is a tutorial with no new theory. Several of its software pointers (1999 FTP sites, Quattro Pro, SYSTAT commands) are dated, but the formulae are not.
