Odds Ratio & Probability Visualizer

See how a regression coefficient (β) translates into an Odds Ratio and shifts the Probability of disease.

The risk of disease for someone with a predictor value of 0.

10%

The 'Estimate' from your R output.

1.00
Calculated Odds Ratio 2.72
Baseline Probability: 10.0%
New Probability: 23.2%

Why does the increase look different?

Notice that while the Odds Ratio stays constant for a given β, the actual jump in Probability depends on where you start (the baseline risk). This is why logistic regression uses a non-linear S-curve!
