TABULATE Procedure
WEIGHT Statement
Specifies weights for analysis variables in the
statistical calculations.
Syntax
Required Argument
 variable

specifies a numeric
variable whose values weight the values of the analysis variables.
The values of the variable do not have to be integers. PROC TABULATE
responds to weight values in accordance with the following table.



Counts the observation
in the total number of observations


Converts the value to
zero and counts the observation in the total number of observations



To exclude observations
that contain negative and zero weights from the analysis, use EXCLNPWGT.
Note that most
SAS/STAT procedures, such as PROC GLM, exclude negative
and zero weights by default.
Note: Prior to Version 7 of SAS,
the procedure did not exclude the observations with missing weights
from the count of observations.
Restrictions:To compute weighted quantiles, use QMETHOD=OS in the
PROC statement.
PROC TABULATE will not compute MODE when a weight variable
is active. Instead, try using PROC UNIVARIATE when MODE needs to
be computed and a weight variable is active.
Interaction:If you use the WEIGHT= option in a VAR statement
to specify a weight variable, then PROC TABULATE uses this variable
instead to weight those VAR statement variables.
Tip:When you use the WEIGHT statement, consider which value
of the VARDEF= option is appropriate.
See the discussion of VARDEF=divisor and the calculation
of weighted statistics in the Keywords and Formulas section of this document.
