abut "Arima"

hi,Why do i can not run Arima ?

I want to run Arima on SAS-University-Edition. My SAS is SAS Studion.

my codes are below;_______

data own.ch1801;

infile "/folders/myfolders/chinab/Ch18-1.txt";

input x @@;

n=_n_;

run;

proc sgplot data=own.ch1801;

scatter x=n y=x/markerattrs=(size=10);

series x=n y=x/lineattrs=(thickness=2);

xaxis integer;

run;

proc arima data=own.ch1801;

identity var=x nlag=12;

run;

There are log below:

NOTE: PROCEDURE SGPLOT used (Total process time):

  real time 15.79 seconds

  cpu time 0.66 seconds

  

NOTE: There were 70 observations read from the data set OWN.CH1801.

72 

73 proc arima data=own.ch1801;

ERROR: Procedure ARIMA not found.

74 identity var=x nlag=12;

75 run;

What is the mean? Is there not Arima in my SAS studio? How can I run Arima?
