# Let's start with our odds ratio for topography from the logit.reg model: µ/ (1 - µ) = 8.09 # Let's rearrange this to isolate µ µ = 8.09(1 - µ) = 8.09 - 8.09µ 8.09µ + µ = 8.09 µ(8.09 + 1) = 8.09 µ = 8.09 / (8.09 + 1) µ = 1 / (1 + (1 / 8.09)) = 0.89 # We obtained the same result without using the exp() function!
