Hi Ben,

❝ So the variance of the estimator of the treatment effect remains the same, even when taking into account the correlation ( :confused: ).

Basically, if you know the ratio and you know the variance estimate from it, then you shouldn't have any degree of freedom to choose a level of correlation between T and R, no?
Perhaps this SAS stuff provides an answer to a question that is slightly different from the one we think we are asking.
