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
enabling you to calculate the predictive probability for specific covariate pattern(s),
and for one dimensional models, ie. models with ONLY ONE predictor variable, you can generate a plot.
You may optionally use summary data in either of 2 ways
- a variable with weights or
- two variables, one with the numbers of success and one with the number of failures
These options is demonstrated in two of the demo dataset.
