You cannot meaningfully quantify "false negatives" of a misuse-based system (IPS or IDS), because that quantity depends on the type of attack mix you use for testing. On the other hand, you can quantify true positives to false positives ratio (signal2noise) on anomaly detection systems in a meaningful way.
