Subject | st: Computing z-scores with zanthro Issue |
Date | Tue, 11 Feb 2014 07:09:48 -0800 |
hello Stata users, I am trying to compute z-scores for children's BMI data. I found the zanthro package and downloaded it. this is the code that I am using and I believe it is the correct one "egen zbmi = zanthro(v3_bmi,ba,US), xvar(v3_chd_ageyears) gender(gender)gencode(m=1, f=2) ageunit(year)" v3_bmi is my bmi variable, ba is the growth chart for 2-20 years old in the US, v3_chd_ageyears, is child age in year, and my gender variable is also included. after I run the code this is the error that I have received: "using data not sorted r(5);" So I sorted the data on the BMI variable and subsequently on the age and ID variables and it still gave me the same error. Does anyone have any suggestions?
