dtable
By default, the
dtable
command places the sample size in its own row:
. sysuse auto, clear
(1978 automobile data)
. dtable mpg, by(foreign)
----------------------------------------------------------
Car origin
Domestic Foreign Total
----------------------------------------------------------
N 52 (70.3%) 22 (29.7%) 74 (100.0%)
Mileage (mpg) 19.827 (4.743) 24.773 (6.611) 21.297 (5.786)
----------------------------------------------------------We can use the following two additional options to relocate it:
. dtable mpg, by(foreign) ///
> sample(, statistics(freq) place(seplabels)) ///
> sformat("(N=%s)" frequency)
----------------------------------------------------------
Car origin
Domestic Foreign Total
(N=52) (N=22) (N=74)
----------------------------------------------------------
Mileage (mpg) 19.827 (4.743) 24.773 (6.611) 21.297 (5.786)
----------------------------------------------------------
The sample() option chooses which sample-level characteristics to
report with statistics(freq) (freq being
"frequency", meaning in this case the number of times each category
(Foreign/Domestic/Total) appears), and the place()
suboption choses their location:
place(items) is the default.
place(inlabels) places it in the column headers (e.g. we’d see
“Domestic (N=52)”).
place(seplabels) places it below the column headers.
The sformat() option formats a particular type of reported
results (in this case, “frequency”) with a given string.
