Title survest.orm

Usage

# S3 method for class 'orm'
survest(
  fit,
  newdata = NULL,
  linear.predictors = NULL,
  x = NULL,
  times = NULL,
  fun,
  loglog = FALSE,
  conf.int = 0.95,
  what = c("survival", "parallel"),
  ...
)

Arguments

fit: result of orm
newdata: data frame defining covariate settings
linear.predictors: linear predictor vector using the reference intercept
x: design matrix
times: times for which estimates are desired; defaults to estimating probabilities of T > t for all uncensored times
fun: optional transformation of survival probabilities
loglog: set to TRUE to use the log-log transformatino
conf.int: a number between 0-1 with the default of 0.95; set to 0 to not compute CLs
what: specify what='parallel' to compute the survival probability at the observed linear predictor and time values, both varying; all possible combinations of these are then not created
...: ignored

Value

a data frame with variables time, surv. If conf.int > 0 the data also contains lower, upper. The variable Xrow indicates the row of the design matrix or the linear predictor element used in getting the current data frame row estimate.
