accuracy

[mickey]

Hello, does anybody know how calculate the Accuracy
http://en.wikipedia.org/wiki/Accuracy_and_precision
with a confusion matrix like this:



95 0 0 0 0 0 0 0 3 0
394 95 52 69 43 32 58 81 124 52
42 0 39 17 0 0 0 0 5 0
30 0 0 60 0 6 0 0 5 0
51 0 0 0 31 0 2 0 10 4
41 1 0 3 0 22 3 0 19 0
30 0 0 0 0 0 63 0 2 0
12 0 2 2 0 0 0 80 3 3
38 0 0 4 0 0 0 0 55 0
36 0 0 0 1 0 1 5 15 42


In particular is it possible from the confusion matrix. I'm not able to apply to the formula to this matrix.

thanks
