ERROR: SAS University Edition Windows, Procedure GPLOT not found, Procedure Autoreg not found!

[aarton13]

Hi guys, I'm new to this program and I don't know how to code in this program. I'm and Accounting Student and I want to use SAS to working on my bachelor thesis. Is there anymistake in these code or something? Pls help, I really don't know what to do 😞

Here attached my code for my project, can anyone help me please?

data arton;
infile datalines eof=last;
input MidSya;
date=_n_-1;
output;
return;
last: do i=1 to 30;
MidSya=.;
date+1;
output;
end;
return;
datalines;

Afaik both procedure belong to modules that are not part of SAS University Edition. Just run

proc setinit;
run;

to see which modules are available. For proc autoreg you need SAS/ETS, for proc gplot the module SAS/Graph is required.

[aarton13]

so what should I do?

[Reeza]

You can use SGPLOT instead of GPLOT, but the code is different. SGPLOT provides better quality graphics and is easier to use overall anyways. You'll find more examples for GPLOT because it's much older, but you should definitely be using SGPLOT these days instead.

[Reeza]

And SAS Academics on Demand does have licenses for these procedures but you're working in the cloud and there's a limit to the size of data. Commercial usage is still prohibited.

If this question is Autoreg you need to find a license.

If the question is gplot you can replace with SGplot.

For example to overlay 4 scatter plots:

proc sgplot data=outp22;
   where date > 1;
   scatter y=u2 x=date; 
   scatter y=p_garch2 x=date; 
   scatter y=MidSya x=date; 
   scatter y=l2 x=date;
run;

Each scatter statement can have different marker attribute options such as marker symbol, color and such.

If you need series then use series instead of scatter and then you have options to control line attributes.

Hi guys thank you for helping, I found the solution for this by requesting a demo of SAS Viya and working perfectly! Thanks!
