Combining multiple ttest in one table

[Michael Eichinger]

Hello,

in an exploratory analysis I compared two subpopulations (z being a dummy variable taking the values 0/1) on a set of observables by calculating ttests:

foreach xvar in a b c d {
ttest `xvar', by(z)
}

I was wondering whether there exists a command that combines the respective means for the different observables and the respective p-values of the ttests into one table:

a mean_a_0 mean_a_1 p-value_a
b mean_b_0 mean_b_1 p-value_b
etc.

Any hints would be greatly appreciated.

Best, Michael

Type in Stata the following:

net from http://www.adeptanalytics.org/radyakin/stata/ttesttab/

See the help file in the above package ttesttab.

Thanks a lot for your help.

By the way: is there an equivalent stata command for ranksum or chi2 in Stata? Eg:

foreach xvar in a b c d {
tab `xvar' z, chi2
}

foreach xvar in a b c d {
ranksum `xvar', by(z)
}

Or a command that returns a table which compares two subpopulations on a set of observables using two-sample t-tests, ranksum test as well as chi2-tests (because eg for some observables the normality assumption is violated)? Your help would be greatly appreciated.
