An integer specifying the value of a numerical sequence for a stratum group that should be used to assign an experimental unit to an arm or a portion of an arm. EXAMPLE(S): StratumGroup#: 0; Position: 0; Arm/Portion of Arm: A StratumGroup#: 0; Position: 1; Arm/Portion of Arm: B If 2 experimental units fall in the same Stratum Group i.e. say 0 in the above example, the first will be assigned Arm A because the current position would be 0 and the 2nd would be assigned Arm B since the current position would be incremented by 1 each time an assignment happens.
