glm.cox: Creates a Cox GLM family object.

In adelie: Group Lasso and Elastic Net Solver for Generalized Linear Models

Creates a Cox GLM family object.

Description

A GLM family object specifies the type of model fit, provides the appropriate response object and makes sure it is represented in the right form for the model family, and allows for optional parameters such as a weight vector.

Usage

glm.cox(
  stop,
  status,
  start = -Inf,
  weights = NULL,
  tie_method = c("efron", "breslow")
)

Arguments

stop	Stop time vector.
status	Binary status vector of same length as stop, with 1 a "death", and 0 censored.
start	Start time vector. Default is a vector of -Inf of same length as stop.
weights	Observation weights, with default NULL.
tie_method	The tie-breaking method - one of "efron" (default) or "breslow".

Value

Cox GLM object.
