A logit transformation as implemented by Ghitza

This logit transformation (from a probability scale to unbounded) does some trimming around extreme values.

logit_ghitza(x, digits = 5)

Arguments

x

input

digits

The number of digits to round by. Larger values indicate more closer to a theoretical inverse logit.

Examples

 logit <- function(x) log(x/(1 - x))
 logit(0.000001)
#> [1] -13.81551
 logit_ghitza(0.000001, digits = 5) # the default
#> [1] -11.51292
 logit_ghitza(0.000001, digits = 1)
#> [1] -2.197225
 logit_ghitza(0.000001, digits = 10)
#> [1] -13.81551
