The GLIMMIX Procedure

WEIGHT Statement

WEIGHT variable ;

The WEIGHT statement replaces $\bR $ with $\bW ^{-1/2}\bR \bW ^{-1/2}$, where $\bW $ is a diagonal matrix containing the weights. Observations with nonpositive or missing weights are not included in the resulting PROC GLIMMIX analysis. If a WEIGHT statement is not included, all observations used in the analysis are assigned a weight of 1.
