Example 45.5 Univariate KDE Graphics

This example uses data from the section Getting Started: KDE Procedure to illustrate the use of ODS Graphics. The following statements request the available univariate plots in PROC KDE:

ods graphics on;
proc kde data=bivnormal;
   univar x / plots=(density histogram histdensity);
   univar x y / plots=densityoverlay;
run;
ods graphics off;

Graphs are requested by specifying the ODS GRAPHICS statement and the PLOTS= option in the UNIVAR statement. Output 45.5.1, Output 45.5.2, and Output 45.5.3 show the kernel density estimate, histogram, and histogram with kernel density estimate overlaid, respectively, produced by the first UNIVAR statement.

Output 45.5.1 Kernel Density Estimate

Output 45.5.2 Histogram

Output 45.5.3 Histogram with Overlaid Kernel Density Estimate

Output 45.5.4 shows the plot produced by the second UNIVAR statement, in which the kernel density estimates for x and y are overlaid.

Output 45.5.4 Overlaid Kernel Density Estimates
