Xu' R2 (Omega-squared)
Description
Calculates Xu' Omega-squared value, a simple R2 equivalent for
linear mixed models.
Usage
r2_xu(model)
Arguments
model
A linear (mixed) model.
Details
r2_xu() is a crude measure for the explained variance from
linear (mixed) effects models, which is originally denoted as
Ω2.
Value
The R2 value.
