Logistic Regression

This web page performs logistic regression, in which a dichotomous outcome is predicted by one or more variables. The program generates the coefficients of a prediction formula (and standard errors of estimate and significance levels), and odds ratios (with confidence intervals).
It extends John Pezzullo's http://statpages.info/logistic.html to handle higher order powers of the explanatory variable; e.g. P/(1–P)=b0+biXi+ci(Xi)2, as well as enable you to calculate Predictive Probability for specific Covariate Patterns.


Model: Dichotomous outcome variable ~ Predictor variable(s)
Numeric variable(s) Obs: always include at least one variable here!
