ilogit: Vectorised inverse logit function
In jedwards24/edwards: James Edwards personal package
ilogit R Documentation
Vectorised inverse logit function
Description
Calculate the inverse logit function exp(x) / (1 + exp(x)). Modified from Faraway package.
The original allowed for some elements to be NA which this does not. I added a check
on x to avoid NaN. This occurs when x is greater than about
750 but, since exp(x) / (1 + exp(x)) = 1 for x>=20, I only check for x > 20 and
output 1 for these cases.
Usage
ilogit(x)
Arguments
x
A numeric vector.
