mpPar: Representing Maximal Procedure

In randomizeR: Randomization for Clinical Trials

Representing Maximal Procedure

Description

Represents the Maximal Procedure.

Usage

mpPar(N, mti, ratio = c(1, 1), groups = LETTERS[1:2])

Arguments

N	integer for the total sample size of the trial.
mti	maximum tolerated imbalance in patient numbers during the trial.
ratio	vector of length K. The total sample number N and all used block lengths (bc) have to be divisible by sum(ratio).
groups	character vector of labels for the different treatments.

Details

Fix the total sample size N and the mti. Afterwards, the patients are assigned to each treatment arm according to the ratio. All randomization sequences are equiprobable.

Value

S4 object of the class mpPar.
