Class for Simulation Results Count Data

Description

A class for simulation results count data.

Details

Use getSimulationCounts() to create an object of this type.

Fields

accrualIntensity: The absolute accrual intensities. Is a numeric vector of length kMax.
accrualTime: The assumed accrual time intervals for the study. Is a numeric vector.
allocationRatioPlanned: The planned allocation ratio (n1 / n2) for the groups. For multi-arm designs, it is the allocation ratio relating the active arm(s) to the control. Is a positive numeric vector of length 1.
conditionalPower: The conditional power at each stage of the trial. Is a numeric vector of length 1 containing a value between 0 and 1.
directionUpper: Specifies the direction of the alternative, only applicable for one-sided testing. Default is TRUE which means that larger values of the test statistics yield smaller p-values. Is a logical vector of length 1.
earlyStop: The probability to stopping the trial either for efficacy or futility. Is a numeric vector.
expectedNumberOfSubjects: The expected number of subjects under specified alternative.
futilityPerStage: The per-stage probabilities of stopping the trial for futility. Is a numeric matrix.
groups: The group numbers. Is a numeric vector.
iterations: The number of iterations used for simulations. Is a numeric vector of length 1 containing a whole number.
maxNumberOfIterations: The number of simulation iterations. Is a numeric vector of length 1 containing a whole number.
overallReject: The overall rejection probability. Is a numeric vector.
rejectPerStage: The probability to reject a hypothesis per stage of the trial. Is a numeric matrix.
sampleSizes: The sample sizes for each group and stage. Is a numeric vector of length number of stages times number of groups containing whole numbers.
seed: The seed used for random number generation. Is a numeric vector of length 1.
thetaH0: The difference or assumed effect under H0. Is a numeric vector of length 1.
