The confusionMatrix function from the {caret} package holds the answer. Most people only glance at Accuracy and then jump straight to Sensitivity, Specificity, and Predictive Values. But they often overlook the fundamentals: No Information Rate, Kappa, and P-values — the very first metrics in the confusion matrix. And here’s the thing: they aren’t just space fillers. Advanced machine learning experts know they’re essential for evaluating a model’s reliability. That’s WHY they’re at the very top of the confusion matrix. Welcome to my VLOG!
