<> You use the result like this: **** clear* set obs 10000 gen x=rnormal() centile x, ce(10) return list di in red `r(c_1)' **** HTH Martin -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Pancho Villa Sent: Montag, 6. Juli 2009 22:01 To: statalist@hsphsun2.harvard.edu Subject: Re: st: RE: Converting a continuous var into a binary var Thank you, Nick and Martin. I abbreviated my problem for simplicity. So much that I'm afraid the feedback I got from you is not helping me much. Actually, my variable y is not binary, but categorical with more than 2 possible values. My y depends on the 10th percentile values of x and z, respectively. (In fact, it depends on the values of other variables, but that's not problematic. This is the simplest description of my problem that can get me helpful feedback from you.) So, it's more like this: y = 0 if x <= 10th percentile of x & z <= 10th percentile of z y = 1 if x <= 10th percentile of x & z > 10th percentile of z y = 2 if x > 10th percentile of x & z <= 10th percentile of z y = 2 if x > 10th percentile of x & z > 10th percentile of z I found that I can do this: centile x z, centile(10) which gives me the 10th percentiles of x and z in the same output. But I don't know how to invoke the result for each variable in my next lines. Truly basic.
