robust.basehaz.phreg: Robust Baseline Hazard Standard Errors

Description

Computes robust (sandwich) standard errors for the cumulative baseline hazard from a phreg object.

Summarizes cumulative baseline hazard estimates from a phreg object, optionally with robust standard errors.

Computes confidence intervals using log or plain transformations, with optional restrictions to positive values or probability scale.

Usage

robust.basehaz.phreg(x, type = "robust", fixbeta = NULL, ...)
summarybase.phreg(object, robust = FALSE, ...)
conftype(
  x,
  std.err,
  conf.type = c("log", "plain"),
  restrict = c("positive", "prob", "none"),
  conf.int = 0.95
)

Value

A list with cumhaz, se.cumhaz, and strata.

An object of class "summary.recurrent".

A list with upper, lower, conf.type, and conf.int.

Arguments

x

point estimate(s).

type

type of standard error (default "robust").

fixbeta

if non-NULL, fixes beta at given value.

...

additional arguments.

object

a phreg object.

robust

logical; if TRUE, uses robust standard errors.

std.err

standard error(s).

conf.type

type of transformation: "log" or "plain".

restrict

restriction: "positive", "prob", or "none".

conf.int

confidence level (default 0.95).
