Dictionary
The Dictionary provides concise definitions of health economics terms, arranged alphabetically for quick reference. Use it to understand unfamiliar terminology or confirm the meaning of a specific term.
C
- CalibrationModel Tuning, Parameter Fitting
- Calibration is the process of estimating or adjusting model parameters so that selected model outputs agree with relevant observed targets under an explicit measure of fit.
- Calibration AssessmentCalibration Check, Goodness-of-Fit Assessment
- An evaluation of how closely a calibrated model's predicted outputs match the observed data used as calibration targets, typically using formal fit statistics.
- Calibration of ExpertsExpert Calibration, Cooke Method
- A method testing experts' ability to estimate quantities with a known true value, then using their performance to weight their judgements on unknown quantities.
- Calibration PlotReliability Diagram, Calibration Curve
- A graphical tool assessing how well a model's predicted probabilities correspond to actually observed outcome frequencies across risk groups.
M
- Model DiagnosticsDiagnostic Checks, Fit Diagnostics
- A set of statistical and technical checks assessing a model's performance, such as poor calibration or unstable results under minor input changes.
O
- Override RateAlert Override Frequency, Alert Dismissal Rate
- The proportion of computerised clinical alerts a provider dismisses without following the recommended action, a key metric for alert calibration.
S
- Seed QuestionCalibration Question, Seed Variable
- A question with a known true answer included in expert elicitation, used to assess and calibrate each expert's accuracy beforehand.
T
- Target QuestionReview Question, Structured Review Question
- A question of genuine interest to a decision-maker with an unknown true answer, posed to experts in structured elicitation, unlike a calibration seed question.
