Cox proprotional hazards univariable models: finalfit model wrapper

Using finalfit conventions, produces multiple univariable Cox Proportional Hazard regression models for a set of explanatory variables against a survival object.

coxphuni(.data, dependent, explanatory)

Arguments

.data

Data frame.

dependent

Character vector of length 1: name of survival object in form Surv(time, status).

explanatory

Character vector of any length: name(s) of explanatory variables.

Value

A list of univariable coxph fitted model outputs. Output is of class coxphlist.

Details

Uses coxph with finalfit modelling conventions. Output can be passed to fit2df.
