st: t-test and missing values

[Navid Asgari <navidstatalist@gmail.com>]

Hi all,

I am facing a simple but a bit confusing situation...

I am running a simple unpaired t-test on equality of means of two
variables, say var1 and var2

var1              var2
------------------------------
1                    3.4
2                    3
3                    1
.                     2
4                    .
0                    .
.

I want Stata to ignore the missing values? In other words, these
records should not be counted as a sample point?

Does "unpaired" option after ttest do this?

Thanks,
Navid
