Traditional deterministic metrics as a function of each other for increasing values (arrows) of the contamination parameter (c = 0.01, 0.02, 0.05, 0.10, 0.25), indicated in light orange, dark orange, pink, violet, and navy, respectively. Though these metrics are functions of the same four variables (see Equations (1), (2), (3), and (4)) and should thus be expected to have consistent relationships at all values of c, the detailed shapes depend on the values of the true and false positive and negative rates; this demonstrative plot thus reflects the proportions of SNe Ia and non-SNe Ia under the DDF observing strategy from Table 1 and our cosmological sample size of 𝒩 = 3000 (see Section 2.2.2). As anticipated, these metrics are degenerate with one another and are insensitive to the contaminating class makeup, only probing the contamination rate.
