multichoise answers and combinations

Gregor Selčan
Hi.

I have 500 respondents and six variables with two values: 0-absent, 1 -
present. I'd like to find out, how many of them answer to each of those 6
variable combinations (of course: only >present< value is counted). For
example:



V1

V1+V2

V1+V3

V1+V4

...

V1+V2+V3

V1+V2+V4

...

V1+V2+V3+V4+V5+V6



If my math is correct, there will be 63 possible combinations. How could I
get corresponded frequencies (number of respondents) of each combination
using SPSS 16?



Thanks in advance,



Gregor Selcan

Gregor:

compute newvar1=v1*10.
compute newvar2=v2*100.
compute newvar3=v3*1000.
compute newvar4=v4*10000.
compute newvar5=v5*100000.
compute newvar6=v6*1000000.
comment the command below assumes that all participants have responses
of  0 or 1 for each variable.
compute totalvars=sum.6(newvar1 to newvar6).
Freq var=totalvars.
The above untested should produce for you all of the different
combinations.
