Transform real values to the logit scale, and the inverse.
vector of numeric values in (0,1) (possibly a probability)
vector of numeric values
The logit transformation is defined as logit(x) = log(x/(1--x)) for x in (0,1).
Numeric value on requested scale.
logit is equivalent to
invlogit is equivalent to
plogis (both R functions in the stats package).
invlogit are used in secr because they are slightly more robust to bad input, and their names are more memorable!
