Re: st: Is there a new zanthro command for the new 2006 WHO growthreference standards?

[Elizabeth Rainwater <erainwat@sfbrgenetics.org>]

Hi Gaby,
  I don't know what you mean by "error", since that is normal output 
for the program. I ran the macro in IC Stata 9.2 and got the same 
messages. Did the program just hang, or was there an actual error 
message? I only had 300 cases, and I remember it taking a couple of 
minutes to run. Then I got more output about flags and where the data 
was saved. Since I am using Stata IC and not SE, the program could not 
calculate prevalences and exited with that error after calculating the 
z-scores. (Francesco <lrdyupa@gmail.com> rightly pointed out this and 
other limitations of the WHO macro, and I agree with him about the 
advantages that an updated -zanthro- would offer.) I am pasting the 
relevant portion of my log file below. I'm sorry, but I can't help with 
your second or third questions - it's a new area for me, and only 
tangentially related to our main research questions. Someone else in 
Stataland may know how different the updated under 5 references are, or 
you may be able to get the old data from the WHO website to compare with 
the new data. I can't comment on -zanthro- because I didn't end up using 
it. (The help file indicated it used US and UK growth standards. Since 
my study population is from rural Nepal, I thought the new WHO standards 
would be a better choice for me.) I'm sorry I don't have anything more 
helpful for you.
Best,
Elizabeth

Note: z-scores are flagged according to the following rules:

                           _zwfl = . if (_zwfl < -5 or _zwfl >5)

Please wait, programme is calculating prevalences.............

..............................................
no room to add more variables
   An attempt was made to add a variable that would have resulted in 
more than 2048 or 2047 variables
   (Stata reserves one variable for its own use).  You have the 
following alternatives:

    1.  Drop some variables; see help drop.

    2.  If you are using Stata/SE, increase maxvar; see help maxvar.
