Chi square between variable and 1 level of another variable

Hi!

How would i test for an association between a variable and just 1 level of another variable?

I only have the 2x2 table.

I have the following code for testing between two variables. Thanks for any help!

DATA PBP2;
DO a=1 TO 2;
DO b=1 TO 2;
INPUT count @@;
OUTPUT;
END;
END;
CARDS;
146 54 159 41
;
RUN;
PROC FREQ;
TITLE6 "Output" ;
WEIGHT count;
TABLES a*b /CHISQ;
RUN;

chi square between variable and 1 level of another

I am not sure what you mean by that type of test? What exactly would you be testing for? In your example which level of which variable are you testing against in the other?

Note that your code does not run as posted.

The CARDS and DATALINE statements must 1) have the Cards or datalines as the only statement on one line of code and 2) the ; or ;;;; in the case of Cards4 or equivalent must be on a line by itself, not at the end or a row of data.
