Fig. 6From: Comparison of Pocock and Simon’s covariate-adaptive randomization procedures in clinical trialsStatistical power of a two-arm CAR design as a function of \(\rho _3\), given \(\rho _4\) from 0.1 to 0.7. In the CAR design, the treatment assignment probability was set as 60%. The first and the second row has the correlation \(\rho _2=0.2\) and 0.1. When the number of factor is zero, it is a CR designBack to article page
