The KDE Procedure |
WEIGHT Statement |
The WEIGHT statement specifies a variable that weights the observations in computing the kernel density estimate. Observations with higher weights have more influence in the computations. If an observation has a nonpositive or missing weight, then the entire observation is omitted from the analysis. You should be cautious in using data sets with extreme weights, because they can produce unreliable results.
