Rubin, Donald B.
Journal of Educational Statistics, 2, 1, 1-26, Spr 77
Assignment of subjects to treatment groups on the basis of a covariate is discussed. It is contended that in making such assignments, consideration should be focused on the conditional expectations of the dependent variable given in the covariate in both treatment and control groups. Statistical development and an example are presented. (JKS)
