If you specify the VARMETHOD=BRR(PRINTH) method-option in the PROC SURVEYMEANS statement, PROC SURVEYMEANS displays the Hadamard matrix used to construct replicates for BRR variance estimation.
If you provide a Hadamard matrix with the VARMETHOD=BRR(HADAMARD=) method-option but the procedure does not use the entire matrix, the procedure displays only the rows and columns that are actually used to construct replicates.
