Functional measures

Definition

Functional measures refer to quantitative assessments that evaluate how well biological systems perform their intended functions under varying conditions. These measures help to determine the robustness of biological networks by analyzing their ability to maintain functionality despite perturbations or stressors, thereby providing insights into the resilience and adaptability of these systems.
