The LOESS Procedure

Syntax

The following statements are available in PROC LOESS:

PROC LOESS <DATA=SAS-data-set> ;: MODEL dependents=regressors < / options > ;; ID variables ;; BY variables ;; WEIGHT variable ;; SCORE DATA=SAS-data-set < ID=(variable list) > < / options > ;

The PROC LOESS and MODEL statements are required. The BY, WEIGHT, and ID statements are optional. The SCORE statement is optional, and more than one SCORE statement can be used.

The statements used with the LOESS procedure, in addition to the PROC LOESS statement, are as follows.

BY: specifies variables to define subgroups for the analysis.
ID: names variables to identify observations in the displayed output.
MODEL: specifies the dependent and independent variables in the loess model, details and parameters for the computational algorithm, and the required output.
SCORE: specifies a data set containing observations to be scored.
WEIGHT: declares a variable to weight observations.
