Initially I used GEE in SPSS, software I longer have access to. In SPSS, QIC values indicated that negative binomial was a dramatically better fit for my data vs. Poisson. Solution1suggested via Stackoverflow link above: uselibrary("sos")andfindFn("{generalized estimating equation...

Fit Negative Binomial Mixture ModelPan Tong (nickytonggmail.com)
2.2 Negative binomial regression The NB model is a generalization of the Poisson model by allowing the Poisson parameter ui to vary randomly following a gamma distribution (Hilbe, 2011). The NB probability density takes the form of (4)fyixi=Γyi+τyi!Γτττ+uiτuiτ+uiyi ...

Part of R Language Collective Report this ad 0 I've been trying to apply cluster-robust standard errors in my calculation of the marginal effects of two predictor variables (main effects and their interaction) in a ZINB model. The code works perfectly when I don't includ...
(glmer model). I don't understand why this is. The experimental design calls for nested random effects so I need to include them. A Poisson lognormal error distribution did not improve the fit. I tried negative binomial error distribution using glmer.nb and couldn’t get it to fit – ...
