The UNIVARIATE Procedure |

WEIGHT variable; |
Required Arguments |
Weight value... | PROC UNIVARIATE... |
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 |
The weight variable does not change how the procedure determines the range, mode, extreme values, extreme observations, or number of missing values. The Student's t test is the only test of location that PROC UNIVARIATE computes when you weight the analysis variables.
Restriction: | The CIPCTLDF, CIPCTLNORMAL, LOCCOUNT, NORMAL, ROBUSTSCALE, TRIMMED=, and WINSORIZED= options are not available with the WEIGHT statement. |
Restriction: | To compute weighted skewness or kurtosis, use VARDEF=DF or VARDEF=N in the PROC statement. |
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.
