Detailed examples of a multitude of regression models, with explanations of how to interpret the output files. If you’re a beginner and need to do a zero-regression Poisson regression because your outcome variable is a count variable (e.g., nr. of crimes or nr. of hours spend playing video games), you can find how to specify a simple model in the user guide. But interpreting the output is a whole different ball-game and this book really provides all the hand-holding you might need.
