summary.ptwiseELtest {survELtest}

Summary function for ptwiseELtest object

Description

Returns a list with a data frame containing the observed uncensored time points, and the decisions, statistics, and critical values of the pointwise EL tests at those time points.

Usage

## S3 method for class 'ptwiseELtest'
summary(object, digits = max(3L, getOption("digits") - 3L), quiet = FALSE, ...)

Arguments

object

the result of a call to the ptwiseELtest function

digits

significant digits to print, the default value is max(3L, getOption("digits") - 3L)

quiet

a logical indicating whether to reduce the amount of output or not, the default value is FALSE

...

for future method

Value

summary.ptwiseELtest returns a list with following components:

• call the statement used to create the ptwiseELtest object

• result_dataframe a dataframe with time_pts in the first column, decision in the second column, stat_ptwise in the third column and critval_ptwise in the fourth column.

  • time_pts a vector containing the observed uncensored time points at which the Kaplan—Meier estimate is positive and less than 1 for each sample.

  • decision a vector containing the decisions of the pointwise EL tests at time_pts. The decision at each of time_pts is 1 for rejection of the null hypothesis that the survival functions are the same at the specific time point, and 0 otherwise.

  • stat_ptwise a vector containing the pointwise EL statistics at time_pts.

  • critval_ptwise a vector containing the critical values for pointwise EL testing at time_pts.
