The 95%-CI for the odds ratio spans from 0.000 to 0.6844, thus an odds ratio of 1.0 is far off and you can reject the null hypothesis, that the values in the contingency table are independent. p = 7.9e-12 means 7.9 × 10 − 12, so very close to zero. Conventionally, the test result is considered 'significant' if p < 0.05. WebMay 6, 2016 · The Wikipedia article on Logistic Regression says:. Logistic regression is an alternative to Fisher's 1936 method, linear discriminant analysis. If the assumptions of linear discriminant analysis hold, application of Bayes' rule to reverse the conditioning results in the logistic model, so if linear discriminant assumptions are true, logistic regression …
