This second edition of Hilbe's Negative Binomial Regression is a substantial enhancement to the popular first edition. The only text devoted entirely to the negative binomial model and its many variations, nearly every model discussed in the literature is addressed. The theoretical and distributional ...

Group differences in STBs were analyzed using a negative binomial regression controlling for age. A group (SA, SI) × valence (positive, negative) analysis of covariance controlling for age was conducted to test differences in processing bias. For both negative and positive words, Bayesian ...
Multiple log-binomial regression models were used, as the outcome was binary; procedure PROC GENMOD was applied for model adjustment. Multivariable analyses were controlled for participants’ age, smoking/non-smoking, mode of delivery, HIV status, nature of HPV infection (clinically defined or ...
These tests, all based on a simple logistic regression model, are a standard Wald test, a continuity-corrected Wald test, and a score test. The Wald test performs poorly in both case–control and TND when VE is high because the number of vaccinated test-...

Differential expression analysis was performed using the edgeR package75 by modeling the raw gene counts predicted by ERβ status with a negative binomial model, taking into account subject and gene-specific dispersion, which were estimated in the CQN method. Differential expression results are ...
