Hi,
When calculating a weighted kappa in the PEPI 4 program, the following
appears:
"When computing a weighted kappa, categories 1 to k will be given the
scores of 1 to k, respectively. Do you want to change these scores? yes/no"
[if yes]
"Enter the new scores:
Cagegory 1: Score:
Category 2: Score:
..........
Category k: Score; "
The way in which the weighting is expressed seems to be in terms of the
points on the scale of measurement rather than the actual weights. The
default option referred to provides a linear weighted kappa. Can anybody
tell me how one should respond to this in order to obtain a quadratic
weighted kappa?
Many thanks indeed.
Julius
