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

maxNumberOfIterations

The number of simulation iterations. Is a numeric vector of length 1 containing a whole number.

seed

The seed used for random number generation. Is a numeric vector of length 1.

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.

iterations

The number of iterations used for simulations. Is a numeric vector of length 1 containing a whole number.

futilityPerStage

The per-stage probabilities of stopping the trial for futility. Is a numeric matrix.

thetaH0

The difference or assumed effect under H0. Is a numeric vector of length 1.

accrualTime

The assumed accrual time intervals for the study. Is a numeric vector.

accrualIntensity

The absolute accrual intensities. Is a numeric vector of length kMax.

groups

The group numbers. Is a numeric vector.

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.

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.

expectedNumberOfSubjects

The expected number of subjects under specified alternative.

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.
