In mjg211/OptGS: Optimal and Near-optimal Group-sequential Designs for Clinical Trials with Continuous Outcomes

Description

opchar() analytically calculates the operating characteristics of a group-sequential clinical trial.

Usage

opchar(
  des = OptGS::des_gs(),
  tau = seq(-des$delta, 2 * des$delta, length.out = 100),
  summary = FALSE
)

Arguments

des	An object of class "OptGS_des", as returned by des_gs, des_nearopt, des_opt, or build. Defaults to des_gs().
tau	A numeric vector indicating the values of τ to perform calculations for. Defaults to seq(-des$delta, 2*des$delta, length.out = 100).
summary	A logical variable indicating whether a summary of the function's progress should be printed to the console. Defaults to FALSE.

Value

A list with additional class "OptGS_opchar". It will contain each of the input variables (subject to internal modification), along with the following elements:

• opchar: A tibble giving the calculated operating characteristics.
