comparing confusion matrices

Dear list,

I need some expert assistance on a geo-statistical question.

I have two maps, first and second choice classification results. And I
have two areas selected within this map. For these areas I calculated
confusion matrices.

However, I want to compare these matrices. I was considering a Mantel
test. However, I do not know if this is correct (sample sizes are not
the same so I normalized both matrices) and ideally I would love to
extract inter row differences rather than the evaluation of the total
matrix (Z-score p-value etc).

Has anyone experience with these kind of statistics (row based
comparison of matrices).

Kind regards,
Koen
