How to find the proc template codes applied in proc lifetest ?

Ivy — Mon, 27 Jun 2022 18:16:14 GMT

Hello,

I am trying to create KM plot based on customized "PRODUCTLIMITESTIMATES" table output from proc lifetest .

Any way I can find the graph part codes in proc lifetest so to customize the codes to create my own plot?

Thanks

Ivy

Yes, but it's not SGPLOT code, it's SGTEMPLATE code, assuming this is related to your previous question. IMO, SGPLOT code is easier to modify/understand.

The code will be in the log.

proc template;
source Stat.Lifetest.Graphics.ProductLimitSurvival;
run;

Thanks very much, Reeza.
That is what I needs.
May I ask another question?
Any way to find the data applied in proc template so I can arrange my data as what is used in proc template?

You can find all of this through ODS TRACE. It specifies the template used and the data set used, which can then be captured via ODS OUTPUT.

Here's some instructions and explanations on how to capture output that is shown.

Agreed, and usually my reference point except OP has their own KM data they want to plot from a customized life estimate table, not from PROC LIFETEST it seems.
