r2_tjur | R Documentation |
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.
