CAS Engine Libref Error

Sai-Reddy — Sat, 16 Jan 2021 07:57:17 GMT

I am running the below code in SAS university Studio & Keep encountering the below Error.

Error: The data set perm.EX1 must be a CAS engine libref.

I am unable to figure out, how to create a CAS engine libref.

**********************************************************************************************;
libname perm '/folders/myfolders/Data'; 

data mycas.ex1;
   length id 8;
   do id=1 to 1000000;
      x1 = ranuni(101);
      x2 = 10*ranuni(201);
      output;
   end;
run;

proc binning data=mycas.ex1 numbin=10 method=quantile; 
input x1-x2; 
output out=mycas.out1; 
run;

CAS is part of SAS Viya which isn't available in SAS UE. SAS UE is based on SAS 9 only.

Is there a way for me to Quantile Binning on SAS UE?

Since proc Binning only accepts CAS libname statements.

@Sai-Reddy - According to this link PROC HPBIN may provide what you want: https://support.sas.com/kb/30/333.html

Proc HPBin does not work on SAS UE, I tried that before doing Proc Binning.

@Sai-Reddy - Perhaps someone more statistically-minded like @Reeza might be able to help.

PROC RANK should give you the same answer.

You could also do it manually via a data step, see this post here for an example:

https://blogs.sas.com/content/iml/2019/08/05/proc-hpbin-bin-variables-sas.html

proc rank data=mycas.ex1 groups=10;
var x1-x2;
ranks rank1 rank2;
run;
