Thank you, Lenz - and one remark: I have forgotten to turn off the weights. Add please this command at the end of my syntax:

WEIGHT OFF.

otherwise it will produce strange results if analyzing the data :-)

Hi Jan

It works, thank you very much!! As a novice in spps-syntax I am really
impressed, how fast you got the answer while I was  twisting my mind for at
least two days in vain . You should earn money with your comments ! ;-)

Regards

Lenz

Hi Lenz,
try this:


WEIGHT BY n .
RANK VARIABLES=n (A) /N INTO relfreq /PRINT=NO /TIES=MEAN .
COMPUTE relfreq = n / relfreq.
EXECUTE.
FORMATS relfreq (F4.2).
VAR LAB relfreq "Relative frequency".

Hello list members,



I have created an (aggregated) sav-file with absolute frequencies (=n) of
case groups. Now I want to calculate relative frequencies (percentage) of
groups in an additional variable. Does anyone of you have an idea how to do
that with syntax ? The result should look like the following example:



Group               n (sum=1000)               relative frequency (?)

A                     100                              0.10

B                     200                              0.20

C                     250                              0.25

D                     50                                0.05

....                     .                                ..





Kind regards



Lenz
