Can someone help me find a package to calculate the FIES score ? I don't seem to find any anywhere.
If there is no package, may someone guide me through the proper equation of the score so I can create a conforming function ?
Thanks a lot.
I managed to find the package. It's called RM.weights
and it uses the Rasch model to create this score. For more details check the link below :
