Column N: = =L3*M3 (drag down)

by predicted probability (highest to lowest). 👉 Select both columns → Data tab → Sort → by Predicted Prob → Descending . Step 2: Choose Threshold Values We will test different classification thresholds (cutoffs). For each threshold, we calculate True Positives, False Positives, etc. 👉 Select both columns → Data tab →

So next time your manager asks, “How good is our model?” – you don’t need to fire up Jupyter. Just open Excel and show them the curve.

Add a new column named Threshold . Start from the highest predicted probability down to the lowest, then add 0.
