Error:ERROR: Matrix bw has not been set to a value.

Hi,

I am new in SAS.

While I am doing Preacher & Hayes's sobel macro using SAS, I got error message. Please see below:

statement : IF at line 182 column 1

ERROR: Matrix bw has not been set to a value.

statement : PRINT at line 182 column 1

ERROR: Matrix op has not been set to a value.

statement : PRINT at line 182 column 1

ERROR: Matrix r2med has not been set to a value.

I executed the command set called called %sobel, with syntax:

%sobel(data=file, y dv, x=iv, m med, boot=z);

I added this syntax at the end of matrix provided by Precher's & Hayes...

For example,

%mend sobel;

%sobel (data=2011.sav, y=BDI, x=WORRY, m=DAILYCOMPGAME, boot=5000);

Any idea?

Can you post a small sample data set that we can run?

Use these data to check your syntax. It runs without error for me on SAS 9.3:

data A;
call streaminit(1);
do i = 1 to 12;
   y = ceil(5*rand("uniform"));
   x = ceil(5*rand("uniform"));
   m = ceil(5*rand("uniform"));
   output;
end;
run;

%sobel(data=work.A, y=y, x=x, m=m, boot=20)

Thank you very much! Sort it out!

And welcome to SAS, by the way. These SAS Communities are a great resource, so I'm glad you've discovered them.
