Conditional Power Results

Class for conditional power calculations

Details

This object cannot be created directly; use getConditionalPower() with suitable arguments to create the results of a group sequential or a combination test design.

Fields

nPlanned

The sample size planned for each of the subsequent stages. Is a numeric vector of length kMax containing whole numbers.

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.

iterations

The number of iterations used for simulations. 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.

simulated

Describes if the power for Fisher's combination test has been simulated. Only applicable when using Fisher designs. Is a logical 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.

thetaH1

The assumed effect under the alternative hypothesis. For survival designs, refers to the hazard ratio. Is a numeric vector.

assumedStDev

The assumed standard deviation(s) for means analysis. Is a numeric vector.
