Dear Statalist:

For a youth population, I am calculating z scores for body mass index (BMI), so I used the following command in Stata:

egen zscore = zanthro(bmxbmi,ba,US), xvar(ridageyr)gender(riagendr) gencode(male=1, female=2)

Next thing I need to do is calculate each participant's age- and gender-specific BMI percentile. After getting their z score, I know I can easily get their percentile by just looking up the corresponding percentile in a z table; however, I have about 3000 participants in my data set so I can't look up each percentile. Any chance you know of a Stata command that I can use that will calculate their percentile based on their z score?

Many thanks,

Paul Loprinzi
