A comparison of methods for quantifying prediction uncertainty in systems biology

Three methods for quantifying prediction uncertainty in ODE models are assessed. Here, prediction uncertainty does not refer to estimated parameters, but to the uncertatinty of state trajectories. The three methods are: Fisher Information Matrix (FIM), Prediction Posetrior (PP), Ensemble Consensus (ENS).
For a small, fully-observed ODE model (α-pinene), all three methods yield nearly same results consistent with the known true trajectories. For a larger, only-partially observed ODE model (JAK2/STAT5), PP and ENS yield better accuracy than FIM. However, even for PP and ENS, confidence levels do not cover the truth.
The computational cost of the three models is differing, especially for large problems: FIM (small), ENS (intermediate), PP (high)
Study design and evidence level
Synthetic data is generated for two examplary ODE models (one smaller, one larger), given a true parameter set. The sample correlation coefficient is used to quantify agreement between predicted and true state trajectories.
Design for Outcome O1
Sample correlation coefficient is compared for the three different methods for the two different models, respectively.
Design for Outcome O2
Computation time is compared for the different models.
