Study Notes

Confusion Matrix Overview

A Confusion Matrix is primarily used to evaluate the performance of a classification model.
It summarizes the results of predictions by contrasting actual versus predicted classifications.

Objectives of a Confusion Matrix

It tests if the discriminant function accurately differentiates between customer segments.
Provides insight into the accuracy and effectiveness of a classification algorithm.
Helps identify the types of classification errors made by the model.

Additional Functions

Does not specifically focus on assessing the statistical significance of the discriminant function.
Not intended for identifying base variables needed for customer classification.
Not focused on evaluating correlations between descriptor variables within a customer segment.
