Missing variables in data generation scripts

You don't seem to create the B variable needed to run the logistic regression.

SAS Code fails with:
1784 /* Logistic regression */
1785
NOTE: PROCEDURE LOGISTIC used (Total process time):
real time 0.00 seconds

ERROR: Variable B1 not found.

1786 PROC LOGISTIC
1787 DATA=BENCH.ANALYSIS;
1788 MODEL B1=N2-N21;
1789 RUN;

Also an ERROR in model scoring as you do not create the N1 Variable in the PREDICT set
