statsmodels.genmod.bayes_mixed_glm.BinomialBayesMixedGLM.vb_elbo_grad# BinomialBayesMixedGLM.vb_elbo_grad(vb_mean, vb_sd)[source]# Returns the gradient of the model’s evidence lower bound (ELBO). Parameters: vb_meanndarrayThe mean vector of the variational approximation, packed as fixed effects parameters, then variance component parameters, then random effect realizations. vb_sdndarrayThe standard deviation vector of the variational approximation, packed in the same order as vb_mean. Returns: mean_gradndarrayThe gradient of the ELBO with respect to vb_mean. sd_gradndarrayThe gradient of the ELBO with respect to vb_sd.
