Delta QAICc
Delta QAICc is defined as the difference between the QAICc for a model and the QAICc for the current minimum QAICc model. Thus, for the minimum QAICc model, the Delta QAICc is zero. The Delta QAICc metric provides a convenient measure of how close a model is to the current minimum QAICc model. The Delta QAICc values are used to construct Akaike Weights, or QAICc Weights.
When c-hat is equal to one, QAICc is shown as AICc in the Results Browser and Delta QAICc is shown as Delta AICc.
This same procedure is used with BIC to create a Delta BIC or Delta QBIC quantity, and corresponding BIC Weights.
