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

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". |
