Log odds

Log odds are the natural log of odds. Many models output log odds before converting to probability.

Definition

Log odds are the natural log of odds. Log odds are common in statistical modeling because they turn multiplications into additions.

Why it matters

Log odds help interpret model scores. Converting log odds to probability produces a predicted probability that can be compared to implied probability.

Common pitfalls

Assuming linearity: A small change in log odds can mean a large change in probability near 0 or 1.
