Confidence band formula
WebJul 2, 2024 · Which gives a confidence interval on the log-odds ratio. Using the invariance property of the MLE allows us to exponentiate to get $$ e^{\beta_j \pm z^* SE(\beta_j)}$$ which is a confidence interval on the odds ratio. Note that these intervals are for a single parameter only. WebIn this Statistics 101 video, we learn the concept of regression confidence interval bands.
