allocationRatioPlanned |
The planned allocation ratio n1 / n2 for a two treatment groups
design, default is 1 . For multi-arm designs, it is the allocation ratio relating the active arm(s) to the control.
For simulating means and rates for a two treatment groups design, it can be a vector of length kMax , the number of stages.
It can be a vector of length kMax , too, for multi-arm and enrichment designs.
In these cases, a change of allocating subjects to treatment groups over the stages can be assessed.
Note that internally allocationRatioPlanned is treated as a vector of length kMax , not a scalar.
