expit: Perform the Inverse-Logit Tranformation

In bstaton1/StatonMisc: Common Functions Used in B. Staton's Code

Description

Performs the inverse-logit transformation. See the details below for exactly what this means.

Usage

expit(x)

Arguments

x	A numeric vector with length >= 1 containing the number in logit space to convert to the [0,1] scale.

Details

The inverse logit tranformation turns any real number (negative to positive infinity) to a number on the [0,1] scale (e.g., the probability scale). I can never remember which transformation the built-in qlogis or plogis functions do, so I wrote my own that are more explicit in their names.

Value

A numeric vector with the same length as x containing the inverse-logit of x.

Examples

expit(x = 1)
expit(x = 0.5)
expit(x = logit(x = 0.5))
