Thanks to Kit Baum, an updated version (v 2.2.0)of -fsum- is now available.

The major changes to -fsum- have been to display the "sum" of "percent" variables; to default the format of the sum to %n.0f, with an option to use decimal format if desired; and to use Stata 8.2 code, making it faster.

The package does not include the tlabel utilities that were in the 2002 release of the package, as I found I never used them. Instead, I used a -mktlabel.ado program and modify it as needed.

Such a program looks like:

program define mktlabel
version 8.2
discard
capture char age[tlabel] "Age (years)"
capture char ahi[tlabel] "Helplessness (5-25)"
capture char ansaid[tlabel] "Flurbiprofen (%)"
capture char antacids [tlabel] "Antacids (%)"
capture char anxiety[tlabel] "Anxiety (0-10)"
capture char arava[tlabel] "Leflunomide (%)"
capture char arava_pat[tlabel] "Arava study observation (%)"
<snip>
end

With a text editor macro, entry of "capture char [tlabel] " is simple. The mktlabel program works in the same way as a list of var labels except that they are char labels.

fsum is a general purpose summary statistic program. Its display can be formatted with appropriate labels and variable formats so that its output can be pasted into a word processor without the need for further alterations within the word processor.

fsum provides summary statistics, including N, # missing, percent missing, mean, variance, standard deviation, standard error, P1, P5, P25, median, P75, P95, P99, minimum, maximum, confidence intervals, sum, and percent for 0/1 variables. It can also display categories of a variable in a manner similar to tabulate. fsum allows Stata labels and special user-defined labels. Display width is automatically adjusted for variable and label length. Column width is adjustable by format, and variable labels are available optionally.
