          1     0         1  
          2     0         1  

I wish to combine results of two different tests in the same table generated by Stata. I wish to learn this technique because the table will need to be generated many times from different datasets. The table I envision has the following structure:

	Column A	-bysort station: bitest uti=.> 2-  
	Column B	-tabulate station correct-
	Column C	confidence intervals for -correct-, stratified by -station-, based on the normal approximation, p+/-1.96(sqrt(p(1-p)/n))

Is this possible to do?




Best wishes,
Michael McCulloch
