Variance Estimation

If the variance method is not Taylor series (see the section Variance Estimation) or if the NOMCAR option is used, by default, PROC SURVEYREG displays the following variance estimation specifications the "Variance Estimation" table:

• Method, which is the variance estimation method

• Number of Replicates, which is the number of replicates if you specify the VARMETHOD=BRR or VARMETHOD=JACKKNIFE option

• Hadamard Data Set, which is the name of the SAS data set for the HADAMARD matrix if you specify the VARMETHOD=BRR(HADAMARD=) method-option in the VARMETHOD=BRR option

• Fay Coefficient, which is the value of the FAY coefficient if you specify the VARMETHOD=BRR(FAY) method-option

• Replicate Weights Dataset, which is the name of the SAS data set that contains the replicate weights

• Missing Levels, which indicates whether a missing category for categorical variables is created depending on whether you specify the MISSING option

• Missing Values, which indicates whether observations with missing values are included in the analysis, depending on whether you specify the NOMCAR option
