Regression coefficients for a multivariate Poisson model predicting the localization (Y = 1) of papers. The rectangles comprise the 95% CI. CI are obtained by adding and subtracting the corresponding SE of each coefficient multiplied by the 97.5th percentile of a standard normal distribution. The category “Europe and North America” includes Australia and New Zealand. The deviance of this specification is 342,443, which is substantially lower than the degrees of freedom (i.e., 547,784), suggesting that the model fits the data adequately.
