WebbWEIGHT Statement. When a WEIGHT statement appears, each observation in the input data set is weighted by the value of the WEIGHT variable. Unlike a FREQ variable, the values of the WEIGHT variable can be nonintegral and are not truncated. Observations with negative, zero, or missing values for the WEIGHT variable are not used in the model fitting. http://gauss.stat.su.se/gu/mm/SAS_PROC_MIXED.pdf

The LATTICE and NESTED procedures fit special types of mixed linear models that can also be handled in PROC MIXED, although PROC MIXED may run slower because of its more general algorithm.

WebbBox-and-whisker plots are a useful means of exploring and presenting data. There are several variations of presentation style any of which may be valid presentations of a data set. Producing high resolution box-and-whisker plots in SAS has only previously been available as an interpolation option through Proc GPLOT with SAS/GRAPH. WebbThe LSMEANS statement computes least squares means (LS-means) of classification fixed effects. As in the GLM procedure, LS-means are predicted population margins —that is, they estimate the marginal means over a balanced population. In a sense, LS-means are to unbalanced designs as classification and subclassification arithmetic means are to …

WebbWEIGHT variable ; The WEIGHT statement names the variable that contains the sampling weights. This variable must be numeric, and the sampling weights must be positive numbers. If an observation has a weight that is nonpositive or missing, then the procedure omits that observation from the analysis.
