Control function for Cox-PH model

Source: R/control_survival.R
control_coxph.Rd

[Stable]

This is an auxiliary function for controlling arguments for Cox-PH model, typically used internally to specify details of Cox-PH model for s_coxph_pairwise(). conf_level refers to Hazard Ratio estimation.

Usage 

control_coxph(
  pval_method = c("log-rank", "wald", "likelihood"),
  ties = c("efron", "breslow", "exact"),
  conf_level = 0.95,
  alternative = c("two.sided", "less", "greater")
)

Arguments

pval_method

(string)
p-value method for testing hazard ratio = 1. Default method is "log-rank", can also be set to "wald" or "likelihood".

ties

(string)
string specifying the method for tie handling. Default is "efron", can also be set to "breslow" or "exact". See more in survival::coxph().

conf_level

(proportion)
confidence level of the interval.

alternative

(string)
alternative hypothesis for the p-value test. Default is "two.sided", can also be set to "less" or "greater" for one-sided testing. Note that one-sided testing is not supported when pval_method = "likelihood".

Value

A list of components with the same names as the arguments.
