Hi
I have run a logistic regression with two categorical variables and the
interaction between the two, variable 1 has 2 categories and variable 2 has
three categories,
I have the odds ratio the interaction term but want to calculate the 85%
confidence interval
Can anyone explain how to get to the confidence interval
Regards
ann
