Thanks for the help! It seems to be working to merge the data files.
For those who are familiar working with anthropometric data analysis, please
take a look at the question and clarify my argument. My question is about the
anthropometric data from the DHS. In the file the variables are defined as :
(HC70)Ht/ A Standard (according to WHO), (HC71) Wt/A Standard deviation (accod.
who). The values does not seem plausible. Here below you may find the summary
for the two variable. My question is, should I apply (manipulate the data and
recalculate with help of stata)according to the WHO growth standard? Since, it
can not be possible that a ghanian child is 145. 48 standard deviation behind a
well nourished child (the reference group)? 
If the case is that I have to calculate my self according to the WHO growth
standard, how do I do this in Stata?
Thanks/Tharshini

Tharshini has two files, one with anthropometric data for children and
one with a listing of all household members that includes the same
children. The data must be combined with -merge-, not -append-.

Hi Tharshini,
Maybe you want to 'append' one file to another if what you need is to add
new variables to your master file.
Cheers,
Evans
