x |
value(s) to be transformed |
min |
Lower end of logit interval |
max |
Upper end of logit interval |
The generalized logit function takes values on [min, max] and transforms them to span [-Inf,Inf] it is defined as:
y = log(p/(1-p))
where
p=(x-min)/(max-min)
The generized inverse logit function provides the inverse transformation:
x = p * (max-min) + min
where
exp(y)/(1+exp(y))
Transformed value(s).
