Re: st: different samples summary table

[Nick Cox <njcoxstata@gmail.com>]

Please use full real names on Statalist. This is explained in

http://www.stata.com/support/faqs/resources/statalist-faq/#tojoin

namely

"You are asked to post on Statalist using your full real name. This is
a long-standing practice on Statalist. Giving full names is one of the
ways in which we show respect for others. Your chances of eliciting a
good reply are greatly diminished if you write and conceal your
identity. Conversely, if you decide just to watch and read on the
list, your email identity remains entirely up to you."

One answer is that when you exclude, don't -drop-.

Consider this simple analogue of your problem

sysuse auto, clear

qui foreach v in mpg weight {
	gen `v'2 = `v' if foreign
	gen `v'3 = `v' if foreign & rep78 > 3
}

tabstat mpg* weight*, s(n mean) c(s)
tabstat mpg* weight*, s(n mean)

This isn't everything you ask for, but there are plenty of
well-documented commands for table export. The one trick here is to
-generate- variables that include only the observations you want,
making use of -if-.

Moreover, those rows should be in a wide format (i.e. from left to right), provide the number of observation affected and the table should be either in Excel or Tex format.
