Hi,
I want to compute McNemar test with the following data:
data abc;
input x $ y $ count;
cards;
Absent Absent 256
Absent Present 0
Present Absent 88
Present Present 0
;
run;
proc freq data=abc;
table x*y/agree;
weight count;
run;
But
log shows that:
NOTE: No statistics are computed for x * y
since y has less than 2 nonmissing levels.
However, with the formula given in book it can be computed
manually. So I am wonder why SAS does not produce the McNemar test statistic.
Is this a software limitation???? ….. or anything else…
Kind Regards,
MADAN
