Webb8 juni 2024 · A mixed-effects logistic regression would be when we have g ( θ) = X β + Z γ with γ ∼ N m ( 0, Ω). A simple example would be if we wanted to do a random intercept, then we could parameterize this as γ ∼ N m ( 0, σ γ 2 I) and Z 's rows are indicators for which group each observation belongs to.
