7 terms matching “Parameter Uncertainty”

F

First-Order UncertaintyStochastic Uncertainty, Individual-Level Variability
Uncertainty arising from variation among individual patients within a modelled population, unlike parameter uncertainty concerning imperfect knowledge of a true average value.

H

Heterogeneity AnalysisSubgroup Variation Study, Effect Heterogeneity Study
An examination of how a model's results vary across different patient subgroups, unlike parameter uncertainty concerning imprecision in a single average population value.

P

Parameter UncertaintyInput Uncertainty, Sampling Uncertainty
Parameter uncertainty is uncertainty about the true values of quantities used as model inputs because those values are estimated from incomplete or imperfect evidence.
Probabilistic Sensitivity AnalysisPSA, Probabilistic Analysis
Probabilistic sensitivity analysis (PSA) characterises parameter uncertainty by assigning probability distributions to uncertain model inputs and propagating joint samples through the model.

S

Second-Order UncertaintyDistributional Parameter Uncertainty, Hyperparameter Uncertainty
Uncertainty about the parameters of a probability distribution itself, such as its true mean and variance, distinct from the variability the distribution represents.
Stochastic ProgrammingOptimisation under Uncertainty, Recourse Programming
An optimisation framework incorporating parameter uncertainty directly into the process, seeking a solution that performs well across possible parameter values.

V

Variability AnalysisVariability Assessment, Variability Decomposition
An examination of how outcomes differ across individual patients due to genuine heterogeneity, unlike parameter uncertainty concerning imprecise population-level averages.
