Represents the Maximal Procedure.
mpPar(N, mti, ratio = c(1, 1), groups = LETTERS[1:2])
S4
object of the class mpPar
.
integer for the total sample size of the trial.
maximum tolerated imbalance in patient numbers during the trial.
vector of length K
. The total sample number N
and
all used block lengths (bc
) have to be divisible by sum(ratio)
.
character vector of labels for the different treatments.
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.
