The LOESSPLOT statement
only supports statistical models of one independent and one dependent
variable. For more information about the fitting methodology, see
the LOESS procedure in the
SAS/STAT user’s guide.
In addition to the loess
curve, the LOESSPLOT statement can compute confidence levels for the
fitted line. To display the confidence levels,
-
use the
CLM= option to declare a name for the confidence level of the
mean
-
use a MODELBAND statement
to refer this name. This statement draws a confidence band from this
information. See
MODELBAND Statement for information
about how to control the appearance of the confidence band.
