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
- Cox Proportional HazardsCox Model, Cox Regression
- The Cox proportional hazards model is a semiparametric survival model that relates covariates to the instantaneous event rate while leaving the baseline hazard unspecified.
G
- Generalized F ModelGen-F Model, Flexible Survival Model
- A highly flexible parametric survival model encompassing several other distributions, including the exponential, Weibull, and log-normal, as special cases.
K
- KnotSpline Breakpoint, Change Point
- A specified point along a variable's range at which a spline function is allowed to change shape, used in flexible parametric survival models.
P
- Parametric Survival ModelParametric Time-to-Event Model, Survival Distribution Model
- A parametric survival model specifies a probability distribution for time to a defined event, enabling estimation of survival and hazard functions and projection beyond observed follow-up under stated assumptions.
R
- Royston-Parmar ModelFlexible Parametric Survival Model, RP Spline Model
- A class of flexible parametric survival models using restricted cubic splines to represent a transformed survival or hazard function while remaining fully parametric.
S
- Semi-Parametric SurvivalSemiparametric Survival Model, Cox-Type Model
- A category of survival models, notably the Cox model, that assumes covariate effects parametrically while leaving the baseline hazard unspecified.
- Survival RegressionTime-to-Event Regression, Survival Model
- A modelling approach estimating the relationship between predictor variables and a time-to-event outcome, including the Cox model and parametric survival models.
