Practical Identifiability of Parameters: Two Sides of the Same Coin

Dr. Harsh Jain
Assistant Professor of Mathematics & Statistics
University of Minnesota Duluth

“Making quantitative predictions with data-driven models – such as in mathematical biology – often requires parameter estimation from imperfect data, raising questions of parameter identifiability and estimability. In this talk, I will first examine parameter identifiability using a case study of two compartmental, ordinary differential equation models of cancer treatment with drugs that are cell cycle-specific (taxol) as well as non-specific (oxaliplatin). Despite the models being structurally identifiable, I demonstrate how ignoring practical identifiability issues can lead to incorrect biological predictions. In the second half of my talk, I will present a model of immunotherapy in the treatment of prostate cancer. Although several model parameters are practically unidentifiable, I demonstrate how this unidentifiability can in fact be exploited to capture individual heterogeneity, and offer an explanation for the very limited success of this kind of therapy in practice.”
