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)

Arguments

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
