So the rate … WitrynaThe logit function is the natural log of the odds that Y equals one of the categories. For mathematical simplicity, we’re going to assume Y has only two categories and code them as 0 and 1. This is entirely arbitrary–we could have used any numbers. But these make the math work out nicely, so let’s stick with them.
