survEndp function

Representation of survival endpoints

Represents survival endpoints in clinical trials.

survEndp(
  cenRate,
  accrualTime = 0,
  cenTime,
  shape,
  scale,
  weights = c(0, 0),
  maxcombo = FALSE
)

Arguments

• cenRate: exponential censoring rate in a survival study.
• accrualTime: duration of the accrual period in a survival study.
• cenTime: total duration of a survival study (maximum length of followup).
• shape: parameter of the Weibull distribution (must be positive)
• scale: parameter of the Weibull distribution (must be positive)
• weights: numeric specifying the weights used for the test. Unless specified an unweighted test is conducted.
• maxcombo: logical specifying if the maxcombo test is used

Returns

A S4 object representing a survival endpoint in a clinical trial.

Details

The survEnd function is a constructor function for an S4 object of the class survEnd representing a survival endpoint in a clinical trial.
