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 |
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
.
