Hi,
I think that you are unfortunately right. In the Graphical User
Interface (GUI) this option is missing. I missed it yesterday and this
morning, too. But there seems to be the possibility of "select if" by
writing a syntax file. On page 130 of the manual you can read:
"13.4 SELECT IF
SELECT IF expression.
SELECT IF selects cases for analysis based on the value of expression.
Cases not selected
are permanently eliminated from the active dataset, unless TEMPORARY is
in effect (see
Section 13.6 [TEMPORARY], page 123).
Specify a boolean expression (see Chapter 7 [Expressions], page 46). If
the value of the
expression is true for a particular case, the case will be analyzed. If
the expression has a
false or missing value, then the case will be deleted from the data stream.
Place SELECT IF as early in the command file as possible. Cases that are
deleted early
can be processed more efficiently in time and space.
When SELECT IF is specified following TEMPORARY (see Section 13.6
[TEMPORARY],
page 123), the LAG function may not be used (see [LAG], page 57)."
It would be great if someone could implement this command in the GUI -
as well as the nonparametrical tests for independent groups, e.g. the
Mann-Whitney-U-Test, and "compute variable if ..." command.
Sincerely,
Oliver Walter

Hi PSPP Users,
I am transitioning from SPSS to PSPP and am having some troubles with
case selection. Specifically, under SPSS, I used to be able to select
cases using a radio button in the Data / Select Cases dialogue box
that stated "Select if condition is satisfied...". However, under
PSPP, I have found that this option is not available, and that you can
only select cases based upon (1) a random sample, (2) case range, or
(3) a filter variable. In other words, there is no option for using
the IF function for selection purposes. I am attaching screenshots
from both programs.
I greatly appreciate any advice that others might have on how to best
make a selection of cases using a conditional IF statement. In short,
I am running analysis of household survey data, but only want to use
data from a handful of the administrative jurisdictions (provinces)
within the larger data set.
Regards,
Allen
PS: I am running GNU pspp 0.10.1-g1082b8
