Hi all,

I try to run hpforest below and keep having errors.

Does anyone know the reason?

Thank you!

proc hpforest data= TEMP5;

target lsm_2/level=binary ;

input HtInInches bmi/level= interval ;

input gender/level=nominal ;

run;

I've never used HPFOREST, but it appears you are defining the target variable as binary. You can check to see if it contains both 0 and 1 values like this:

proc freq data = TEMP5;
  table lsm_2;
run;

I recoded it and made error from coding.
