How do you select performance metrics?

How do you select performance metrics?

To evaluate such a model, we can choose any of the various metrics available to us, like Accuracy, Sensitivity, Specificity, Precision, F1 Score, Probability Threshold, AUC, ROC Curve . It is important that this choice is backed by analytical reasoning. Often, we choose Model Accuracy to evaluate the model.

What is model performance metrics?

Most model-performance measures are based on the comparison of the model’s predictions with the (known) values of the dependent variable in a dataset. For an ideal model, the predictions and the dependent-variable values should be equal. In practice, it is never the case, and we want to quantify the disagreement.
