Add

Tableout outest=Est

to the PROC statement

And output dataset named EST will have the pvalues among a lot of the other model statistics. Look at the value of _type_ the find the pvalue.

I chaged my code to the following based on your suggestion:

proc reg data=yearlyTrend_calculation;
model yearlyAvg=a0 a1;
output out=regres p=yhat r=e stdp=sd;
Tableout outest=Est;
run;

but when I want to print the result : proc print data=Est; run; , I got the following error:
run;

 182         Tableout outest=Est;
             ________
             180
 NOTE: The previous statement has been deleted.
 ERROR 180-322: Statement is not valid or it is used out of proper order.

A Proc Statment is the bit that starts with Proc and ends with a ";" .

So you want

proc reg data=yearlyTrend_calculation  Tableout outest=Est;
 model yearlyAvg=a0 a1;
 output out=regres p=yhat r=e stdp=sd;
run;
