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.
F
- Flexible Parametric ModelSpline-Based Survival Model, Flexible Hazard Model
- A flexible parametric model is a fully specified regression model that represents a transformed survival function with smooth functions of time, commonly restricted cubic splines, so complex hazards and time-varying effects can be estimated and extrapolated.
R
- Restricted Cubic SplineRCS, Restricted Cubic Splines
- A restricted cubic spline is a smooth piecewise cubic function of a continuous predictor constrained to be linear beyond its outer knots, allowing regression models to represent nonlinear associations without prescribing one global polynomial shape.
- 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.
