Feb 12, 2015 at 7:02 comment added Sven Hohenstein @Here, symmetry is related to the absolute difference to a probability of $0.5$ or a logit of $0$. If probability is $0.5 + x$, the logit is $0 + y$; If probability is $0.5 - x$, the logit is $0 - y$. Here, $\text{sign}(x) = \text{sign}(y).$
Feb 12, 2015 at 6:59 comment added Sven Hohenstein @Leaf Since there are only two groups, A and B, the probability for group A is $1 - 0.55 = 0.45$.
Feb 12, 2015 at 3:55 comment added user 31466 There is a probability of about $0.55$ that a case belong to group B. When will it belong to group A ?
Feb 12, 2015 at 3:50 comment added user 31466 " Logits of $-0.2$ and $0.2$ correspond to probabilities of $0.45$ and $0.55$ respectively." How does it imply that logit distribution is symmetric?
