computeBootObj {safestats}

Computes the bootObj for sequential sampling procedures regarding nPlan, beta, the implied target

Description

Computes the bootObj for sequential sampling procedures regarding nPlan, beta, the implied target

Usage

computeBootObj(
  values,
  beta = NULL,
  nPlan = NULL,
  nBoot = 1000L,
  alpha = NULL,
  objType = c("nPlan", "nMean", "beta", "betaFromEValues", "logImpliedTarget",
    "expectedStopTime")
)

Arguments

values

numeric vector. If objType equals "nPlan" or "beta" then values should be stopping times, if objType equals "logImpliedTarget" then values should be eValues.

beta

numeric in (0, 1) that specifies the tolerable type II error control necessary to calculate both "n" and "phiS". Note that 1-beta defines the power.

nPlan

integer > 0 representing the number of planned samples (for the first group).

nBoot

integer > 0 representing the number of bootstrap samples to assess the accuracy of approximation of the power, the planned sample size(s) of the safe test under continuous monitoring.

alpha

numeric in (0, 1) that specifies the tolerable type I error control –independent on n– that the designed test has to adhere to. Note that it also defines the rejection rule e10 > 1/alpha.

objType

character string either "nPlan", "nMean", "beta", "betaFromEValues", "expectedStopTime" or "logImpliedTarget".

Value

bootObj

Examples

computeBootObj(1:100, objType="nPlan", beta=0.3)
