Question

What is the generalized R-Squared?

Answer 1

`R_("GEN")^2 = 1 - ((L(0))/(L(hat theta)))^(2/n)`

Explanation:

The generalised `R^2` is defined as

`R_("GEN")^2 = 1 - ((L(0))/(L(hat theta)))^(2/n)`

where `L ( 0 )` : the likelihood of the model with only the intercept

`L ( hat theta )` : the likelihood of the estimated model
and `n` : sample size.
