Title: | Treatment Allocation in Clinical Trials by the Maximal Procedure |
---|---|
Description: | Performs treatment allocation in two-arm clinical trials by the maximal procedure described by Berger et al. (2003) <doi:10.1002/sim.1538>. To that end, the algorithm provided by Salama et al. (2008) <doi:10.1002/sim.3014> is implemented. |

This function produces a treatment assignment sequence generated according to the maximal procedure of Berger et al. (2003). It is an implementation of the algorithm proposed by Salama et al. (2008).
mpboost(N1, N2, MTI = 2L)
mpboost(N1, N2, MTI = 2L)
N1 |
An integer specifying the size of the sample assigned to treatment 1. |
N2 |
An integer specifying the size of the sample assigned to treatment 2. |
MTI |
An integer specifying the maximum tolerated imbalance (MTI). The default is 2. |
A vector of N1 1's and N2 2's representing the allocation sequence.
See the package's vignette for more details and further examples of the use of the function.
