See also: | For information on calculating weighted statistics and for an example that uses the WEIGHT statement, see WEIGHT |
WEIGHT variable; |
Required Arguments |
Weight value... | PROC STANDARD... |
0 | counts the observation in the total number of observations |
less than 0 | converts the weight value to zero and counts the observation in the total number of observations |
missing | excludes the observation from the calculation of mean and standard deviation |
Tip: | When you use the WEIGHT statement, consider which value of the VARDEF= option is appropriate. See VARDEF= and the calculation of weighted statistics in Keywords and Formulas for more information. |
Note: Prior to Version 7 of the SAS System,
the procedure did not exclude the observations with missing weights from the
count of observations.
