Computes the actual and predicted effectiveness of a given algorithm.

This function computes the actual and predicted effectiveness of a given algorithm for different tolerance values.

algo_effectiveness_poly(mod, num = 1)

Arguments

mod

A fitted mirt model using the function irtmodel or R package mirt.

num

The algorithm number

Value

A list with the following components:

effective

The x,y coodinates for the actual and predicted effectiveness curves for algorithm num.

predictedEff

The area under the predicted effectiveness curve.

actualEff

The area under the actual effectiveness curve.
