In randomizeR: Randomization for Clinical Trials

Representing any randomization procedure

Description

Represents any randomization procedure for a two-armed clinical trial.

Usage

createParam(method, N, mti, bc, rb, p, ini, add, filledBlock)

method	method that is used to generate the (random) allocation sequence. It can take values PBR, RAR, HAD, PWR, EBC, BSD, CR, TBD, UD, and MP.
N	integer for the total sample size of the trial.
mti	maximum tolerated imbalance in patient numbers during the trial.
bc	vector which contains the lengths k_1,...,k_l of each block. This means that the vector bc will have one entry for each block.
rb	block lengths of the blocks that can be selected equiprobable at random.
p	success probability of the biased coin (e.g. in Efron's Biased Coin Design).
ini	integer representing the initial urn composition.
add	integer representing the number of balls that are added to the urn in each step.
filledBlock	logical whether the last block should be filled or not.
