Analyses examined associations between alcohol display category and (1) AUDIT problem drinking category using logistic regression, (2) AUDIT score using negative binomial regression, and (3) alcohol-related injury using the Fisher exact test . If you'd like to learn more about the different models available for Count data, you can download a recording of the webinar: Poisson and Negative Binomial Regression for Count Data. Could count data be normalized somehow- e.g. A robustness check estimating Generalized Estimation Equation (GEE) population-averaged models allowing for an autoregressive correlation of order one. JEL-Classification: O31, O32, O33, O34. I'm very interested in collecting this type of time series discrete count data but am new to the statistical methods involved. Keywords: R&D Collaboration, Knowledge Exchange, Patents, Innovation, Count. Since the outcome variable “absenteeism” is a count variable, Poisson, Quasi-Poisson, Negative binomial and Zero inflated models are applied and compared on the basis of Log likelihood, AIC, regression coefficients and standard errors of the best fit. Time series analysis methods to count data? It was found For example, in social data analysis, Poisson regression models were used to assess the effects of parental and peer approval of smoking on adolescents' current level of smoking (Siddiqui et al., 1999). Exchange alliances drive 'portfolio patenting', resulting in fewer forward citations.
