Quinn,
If you put the results you want into a Stata matrix, you can use the program -frmttable- (userwritten, by me, at SSC) to convert this to a formatted Word or TeX table.
The following example creates a table like the one you describe:
sysuse auto, clear
mat T = J(2,4,.)
ttest mpg, by(foreign)
mat T[1,1] = r(mu_1)
mat T[1,2] = r(mu_2)
mat T[1,3] = r(mu_1) - r(mu_2)
mat T[1,4] = r(p)
ttest weight, by(foreign)
mat T[2,1] = r(mu_1)
mat T[2,2] = r(mu_2)
mat T[2,3] = r(mu_1) - r(mu_2)
mat T[2,4] = r(p)
mat rownames T = mpg weight
frmttable using ttest.doc, statmat(T) varlabels replace ///
ctitle("", Sample1mean, Sample1mean, Difference, "(p-value)")
The -frmttable- command displays the table below and saves it to the Word file ttest.doc:
------------------------------------------------------------------
Sample1mean Sample1mean Difference (p-value)
------------------------------------------------------------------
Mileage (mpg) 19.83 24.77 -4.95 0.00
Weight (lbs.) 3,317.12 2,315.91 1,001.21 0.00
------------------------------------------------------------------
If you want to get fancy, you can change fonts and other formatting, as well as merge or append this table with new results.
