Dear colleagues,

Is possible to run a bootstrapped  t-test on the paired-observation variables preert and postrt.  I tried the command line below 

bs "ttest preert=postrt" "_b[preert] _b[postrt", reps(50) n(10)

The error message I am getting says:
error when command executed on original dataset
invalid syntax
r(111);

Many thanks for your help in advance.

Regards,
Amani
