Hello,
Could someone show me the codes for grouping a continuous variable as a categorical variable? for instance, BMI in my dataset is a continuous variable, if I want to redefine the variable in a new variable bmigp as
bmigp = 1 if bmi<25
bmigp= 2 if 25<= bmi< 30
bmigp= 3 if bmi>=30
what should the codes be?
Thanks in advance!
Jason
