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.
, as well as enable you to calculate Predictive Probability for specific Covariate Patterns.
- First row must contain column names
Use short informative names without special characters
- List (comma separated) Numeric variables below
- Non-Numerical variable is treated as categorial
- Write copy/paste (Excel) or load CSV file
