PROC Univariate CDFPLOT

[ Edited ]

I'm having trouble running the following code in SAS 9.4:

 

proc univariate data=lea;
var starttime;
cdfplot starttime / vref=1779111938;
run;

The code runs and I get the default univariate output as well as the plot but the reference line is not on there. The CDFPLOT part is in red text in the editor and 'vref' is not in blue. This leads me to believe that the procedure is not working propery as other options such as HISTOGRAM and QQPLOT do work (turn blue and produce plots).

Re: PROC Univariate CDFPLOT

Using SAS UE, which is 9.4, I don't see any issues.

 

Here's my code, if you have issues with this then I would highly suggest you contact SAS Tech support. 

 

Do note that if you have your VREF out of the range of your data then it won't show up on the graph.

 

proc  univariate data=sashelp.class;
var weight;
cdfplot weight/vref=40;
run;quit;

proc  univariate data=sashelp.class;
var weight;
cdfplot weight/vref=150;
run;quit;

Re: PROC Univariate CDFPLOT

Thank you. I erroneously interpreted VREF to mean a vertical reference line, not for the vertical axis.

Re: PROC Univariate CDFPLOT

Don't worry about certain keywords appearing in red. Sometimes the color-coding in a program edsitor is not perfect. CDFPLOT is a valid statement, as you can see by consulting the documentation for PROC UNIVARIATE.

 

Regarding the REF= statement, your code will be more understandable and less prone to error if you specify the reference line in a human-readable format. For example:

 

cdfplot starttime / vref='17May2016:13:45:38'dt;

 

Make sure that you use the same format as is used for the STARTTIME variable. For example, another possibility is 

vref='17May2016'd;
