r2_tjur: Tjur's R2 - coefficient of determination (D)
Description
This method calculates the Coefficient of Discrimination D
(also known as Tjur's R2; Tjur, 2009) for generalized linear (mixed) models
for binary outcomes. It is an alternative to other pseudo-R2 values like
Nagelkerke's R2 or Cox-Snell R2. The Coefficient of Discrimination D
can be read like any other (pseudo-)R2 value.
Usage
r2_tjur(model, ...)
Value
A named vector with the R2 value.
Arguments
model
Binomial Model.
...
Arguments from other functions, usually only used internally.
