Table 1.

Optimal allocation matrices for cross‐sectional designs with D = 2. The optimal allocation matrices in the case I={6}, C={C6}={10}, M=M6,6={10}, and σ 2 = 1, with w = 0 and β = 1 are shown for a range of possible values of E(ρ). No restrictions are placed on X other than the identifiability of Equation (1). Each allocation matrix was identified via our exhaustive search method and matches that identified by previous research
