Frequently asked questions
What is the logit and odds calculator used for?
Convert a probability into odds and log-odds, as used in logistic regression. It helps with questions such as “logit function”, “log odds”, “probability to odds”.
What is the formula for the logit and odds calculation?
Log-odds (logit) = ln(p / (1-p)). Odds = p / (1-p). Here p is probability.
What inputs do I need for the logit and odds calculator?
You need probability. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the logit and odds calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the logit and odds result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
