What is the Logistic Regression Calculator?

The Logistic Regression Calculator is a statistical tool that models the relationship between a binary outcome (Y = 0 or 1) and one independent variable (X). By entering paired X and Y values, the calculator estimates the logistic regression coefficients—intercept (b0) and slope (b1)—using gradient descent. These coefficients define the logistic function, which predicts the probability of the outcome being 1 for any given X value. The calculator also provides predicted probabilities for each input, helping users understand the likelihood of outcomes and the direction of influence of the independent variable.

How to Use:

1. Enter X Values: Input numeric predictor values, separated by commas.
2. Enter Y Values: Input corresponding binary outcome values (0 or 1), separated by commas.
3. Click “Calculate”: The calculator estimates the intercept and slope, then predicts probabilities for each X.
4. Interpret Results: Use the slope to understand how changes in X affect the likelihood of Y = 1, and use the predicted probabilities for prediction or classification purposes.
