I want to check p-value in chi-Square test, and this is my code in SAS.
data dataA;
input Ball $ observed;
datalines;
A 1
B 0
C 0
D 0
E 9
;
run;
proc freq data=dataA;
tables Ball / chisq;
weight observed;
run;
Here is a problem. This Chi-square test did not include when value is 0. Actually, DF is 4, but now it's 1.
The below calculation is what I want (Chi-square should be 31), including 0 values.
How can I include the category with 0 value so that DF becomes 4, not 1? and Chi-squared becomes 31, not 6.4?
Thanks!!
You need to use ZEROS option on the WEIGHT statement.
proc freq data=dataA;
tables Ball / chisq;
weight observed / zeros;
run;
