Could you make a comparison video between odds ratio (OR) and Marginal Effects, their interpretation seems to be different.

I love these videos on a single topic, thank you.
1st question: The formula used for the calculation of the confidence interval assumes an underlying normal distribution. Is this correct?
2nd question: If so, don’t rare events often show other distributions?

Hi, you lost me for a moment at 5.42/13.11 where you calculated upper and lower CL - could you please layout further, how you achieved 43.37
