Software for Detection Theory
In this appendix, we describe software available for doing the calculations presented in the book. The descriptions take two forms. First, the listing of a program for basic calculation (e.g., of yes-no d', c, and β) is given. Second, we list Web sites from which useful programs can be downloaded. We thank the colleagues who have agreed to publicize their sites in this way.
The following Pascal program calculates d', c, and β for frequency data typed into a keyboard. It consists of a subroutine for estimating z and a simple driver program. To deal with perfect proportions, it uses the l/2, N - l/2 rule described in chapter 1.
