Is there a way to plot loglogs (LLS) graph with very large data in SAS?

[medic]

Hello,

I'm trying to plot a loglog vs log graph using PROC LIFETEST in SAS, so that I can check the proportional hazard assumption with the data.

However, since I'm dealing with a very large data (appx. 7-million records) the system stops running with the error saying:

ERROR: JVM(Java virtual machine) exception. java.lang.OutOfMemoryError: Java heap space.

After with some searching, I increased the memory capacity from 128m to 1024m but the problem remains same.

Would there be any better options to plot the graph? or is there any other way (that my computer can handle) to check the proportional hazard assumption?

Thanks in advance

Did you try just outputting the results to a dataset and writing your own code to make a graph?

[medic]

that seems reasonable. Thanks.
Could you help a little more about how I can get the results as a dataset?

Add the line below to your code 🙂

ods output LogNegLogSurvivalPlot=LogNegLogSurvivalPlot;
