In hypothesis tests of TPR_1 vs TPR_0 at fixed FPR, or
FPR_1 vs FPR_0 at fixed TPR, this computes the
equivalent Z-test effect size. This can then be passed
the effect.size
argument in a call to
pwrFDR
or controlFDP

FPR0 |
When the TPR is fixed, the FPR under the null. Otherwise the fixed FPR. |
FPR1 |
When the TPR is fixed, the FPR under the alternative. Otherwise left blank. |
TPR0 |
When the FPR is fixed, the TPR under the null. Otherwise the fixed TPR. |
TPR1 |
When the FPR is fixed, the TPR under the alternative. Otherwise left blank. |
b |
Nominal slope of the ROC at FPR0. Taken to be 1 by default. |
The equivalent Z-test effect size in a hypothesis test for difference in TPR at fixed FPR or difference in FPR at fixed TPR
