Hello to everybody on the list:

 

I hope somebody could help me with this.

 

I have a test which have two cut scores (set by a panel of experts using
bookmark). So I have tree performance groups.

 

The question is how could I calculate a classification consistency index for
my tree groups?. I suspect ist related to the persons measure error, but I’m
not sure about how to do it.

 

Thank you very much.

 

Andres
