inv_logit: Generalized inverse logit function

In jSDM: Joint Species Distribution Models

Generalized inverse logit function

Description

Compute generalized inverse logit function.

Usage

inv_logit(x, min = 0, max = 1)

Arguments

x	value(s) to be transformed
min	Lower end of logit interval
max	Upper end of logit interval

Details

The generalized inverse logit function takes values on [-Inf,Inf] and transforms them to span [min, max] :

y = p' (max-min) + min

where

p =\frac{exp(x)}{(1+exp(x))}

Value

y Transformed value(s).

Examples

x <- seq(0,10, by=0.25)
xt <- jSDM::logit(x, min=0, max=10)
cbind(x,xt)
y <- jSDM::inv_logit(xt, min=0, max=10)
cbind(x,xt,y)
