R Documentation

Proportional hazards partial likelihood, using Breslow method for ties, excluding some observations.

This function implements the approximate conditional inferential approach of Kolassa and Zhang (2019) to proportional hazards regression.

newllk(
  beta,
  fit,
  exclude = NULL,
  minus = FALSE,
  keeponly = NULL,
  justd0 = FALSE,
  cc1 = 0
)

`beta`	parameter vector.
`fit`	Output from a Cox PH regression, with x=TRUE and y=TRUE
`exclude`	data set with stratum and patient number to exclude.
`minus`	logical flag to change sign of partial likelyhood
`keeponly`	variables to retain. Keep all if this is null or NA.
`justd0`	logical variable, indicating whether to calculate only the function value and skip derivatives.
`cc1`	Continuity correction for first component of the score.
