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.

Schoenfeld ResidualSchoenfeld Test, Cox Residual

A residual specific to the Cox model, calculated at each event time, used to test whether the proportional hazards assumption holds.

Survival AnalysisSurvival Methods, Time-to-Event Analysis

Survival analysis examines the time from a defined origin to an event such as death, disease progression, hospitalisation, recovery or treatment discontinuation.

Survival FunctionSurvivor Function, Survivorship Function

A function giving the probability that a person survives without the event of interest beyond a specified point in time.

Time-Varying HazardTime-Dependent Hazard, Non-Constant Hazard

A hazard rate that changes in magnitude over follow-up, unlike a constant hazard that stays the same at every point.

Weibull ModelWeibull Survival Model, Weibull Regression

A survival model based on the Weibull distribution, representing an increasing or decreasing hazard over time, though restricted to a monotonic pattern.
