    A Systematic Methodology for Parameter Subset Selection and Identification: Cardiovascular Function in Heart Transplant Patients.

    Résumé : Tackling an open biological question is typically done by obtaining experimental or clinical data and then using a biosimulation model to analyze the data to gain understanding. However once the biosimulation model is chosen, care must be taken to select parameters in the model that can be adjusted to yield a unique set of values for each dataset. If the selected parameter subset is unique then we have confidence that there is actually a difference when comparing the values across experiments, patients or animals. We have assembled an approach which utilizes sensitivity analysis and structured correlation methods to select a model parameter subset that can be uniquely identified using optimization methods to match experimental datasets. A final check to ensure identifiability in the neighborhood of the optimized parameter values using a delayed rejection adaptive metropolis (DRAM) algorithm will also be presented. This workflow will be illustrated in the context of identifying cardiovascular function in heart transplant patients during recovery. We will also discuss how to extend this methodology to choose between different biosmulation models subject to a given dataset.
