Each row represents an object or an individual. The cell entries is the number of raters
that evaluates the object in question to be in the specific category.
Each row must sum up to the same, i.e. the row-sum of the first row!
E.g.
- 5 objects/patient/X-rays to evaluate
- 3 categories
- 4 raters
1,2,1
2,2,0
0,1,3
3,1,0
4,0,0
Here the row-sum of the first row is 4, i.e.
4 raters.
The first object is evaluated to be in category A by 1 rater, in category B by 2 raters
and in category C by 1 rater. Etc ...
All raters agrees the last object to be in category A
