WebPosterior predictive checks mean "simulating replicated data under the fitted model and then comparing these to the observed data" (Gelman and Hill, 2007, p. 158). Posterior predictive checks can be used to "look for systematic discrepancies between real and simulated data" (Gelman et al. 2014, p. 169). performance provides posterior predictive … Webggpredict_glmmTMB.R This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below.

WebMar 8, 2024 · The DHARMa R package (disclaimer: I develop this package) has a zero-inflation test for GLMMs, including glmmTMB, that you can use to test your model. However, see notes in the vignette about zero-inflation: when fitting GLMMs with variable dispersion, zero-inflation often shows up as underdispersion, so the most reliable test is usually to … WebPredict the outcome variable at different regressor values (e.g., college graduates vs. others), and compare those predictions by computing a difference, ratio, or some other function. comparisons() can return many quantities of interest, such as contrasts, differences, risk ratios, changes in log odds, slopes, elasticities, etc. comparisons(): unit … Web> > When the "probit" link is used to fit the model, predict.glmmTMB() seems to work just fine. > > I have stared a bit at the code for predict.glmmTMB() but the subtleties are too … sephora southgate hours
