Imbalance score and allocation predictability of the three PS methods: the PS\(_{p=0.5}\) method (rows 1 and 2), the PS\(_{q=0.5}\) method (rows 3 and 4), and the PS\(_{t=0.8}\) method (rows 5 and 6), as a function of the total sample size and the number factors in the CAR for a study with 3 treatments. The range approach (left) and the SD approach (right) are used in the covariate imbalance score calculation
