Label2 error

[GKati]

Hello, 

The code below is from the following link (https://stats.idre.ucla.edu/sas/faq/how-can-i-bootstrap-estimates-in-sas/) for bootstrapping. I am trying to run this code, but I get an error msg in the beginning. "Label2" seems to be uninitialized. 

Basic statistics are saved into dataset t0, and we are trying to save the value where the  label says RSquare.

My code is the following:

ods output FitStatistics = t0;

proc glm data=data_predict;

class year (ref="2010");

model cost=contract|year|age|female /solution;

run;

quit;

*store the estimated r-square;

data _null_;

set t0;

if label2="RSquare" then

call symput('r2bar', cvalue2);

run;

Open your t0 data set and see which variable has the value RSQuare and replace it with that variable name instead.
