Conditional summary using PROC MEANS Part 2

d6k5d3 — Sun, 03 Feb 2019 08:53:39 GMT

I have the following dataset:

data have;
  input dv1  dv2 dv3  dv4;
datalines;
1 0 1 0
0 0 1 -1
1 -1 0 0
0 1 1 1
0 0 1 -1
1 1 0 0
0 0 0 0
1 0 1 1
0 0 1 1
1 1 1 0
1 0 0 0
run;

Using PROC MEANS I want to know the following frequencies:

dv2>0

dv2<0

dv4>0

dv4<0

dv2= 0 when dv1= 1

dv4= 0 when dv3= 1

How can I get them?

Much thanks again.

Regards.

It has to be PROC MEANS? You can't use a more appropriate tool like PROC FREQ? In PROC FREQ, the answer is easy. Why make extra work by forcing a tool like PROC MEANS to do something that it wasn't designed to do?????

Hi @d6k5d3,

Try this:

proc format;
value sign
low-<0  = '<0'
0       = ' 0'
0<-high = '>0';
run;

proc means data=have noprint;
format dv2 dv4 sign.;
class dv4 dv2 dv1 dv3;
types dv4 dv2 dv2*dv1 dv4*dv3;
output out=want;
run;

proc print data=want noobs;
run;

The output contains the requested counts (highlighted below):

dv4    dv2    dv1    dv3    _TYPE_    _FREQ_

Would you please tell me how I can do this using PROC FREQ? I didn't have the idea about using it. The only other way I could figure out was PROC SQL which for some reasons I cannot use.

Much thanks.
