SDA 3.4 Documentation for DESCRIBE
describe - generate a description of a variable
describe -b filename
DESCRIBE displays the text, labels, and a frequency distribution
for a variable (provided there are no more than 256 distinct
category values). Output from the program is in HTML, which can
be viewed with a Web browser.
Ordinarily this program is invoked by the new SDA user interface
for viewing a selected variable, and the user does not have to
deal with the keywords given in this document. However, it is
possible to run the program in batch mode independently of the
Meaning of the option flag:
- -b filename
- The name of the batch command file is specified to the
program after the ‘-b’ option flag.
The batch command file contains specifications for the analysis.
These specifications are given in the form "keyword = something"
with one keyword per line. Keywords may be given in any order,
either in upper or in lower case. The valid keywords are as
follows (with significant characters shown in capital letters):
Keyword Possible Specification Default (if no keyword)
STUdy= path of dataset directory Look for variables only in
VAR= variable name REQUIRED
GVARCase= LOWER or UPPER Do not convert the variable
name to lower/upper case
SAvefile= filename to receive output Output sent to screen
(overwrite existing file) (standard output)
LAnguagefile= Name of file with non-English English labels on
labels and messages output
EXAMPLE OF A BATCH FILE
The SDA dataset is in the directory ’/sa/sdatest’. The results
will overwrite the file named after the ‘savefile=’ keyword, if
the file already exists.
study = /sa/sdatest
var = spend
savefile = mytables.htm
